Read this chapter to help guide you through the initial setup of your new T35 Transformer Protection System.

1.1.1 CAUTIONS AND WARNINGS

Before attempting to install or use the device, review all safety indicators in this document to help prevent injury, equipment damage, or downtime.

The following safety and equipment symbols are used in this document.

Indicates a hazardous situation which, if not avoided, will result in death or serious injury.

Indicates a hazardous situation which, if not avoided, could result in death or serious injury.

Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.

Indicates practices not related to personal injury.

a) GENERAL CAUTIONS AND WARNINGS

The following general safety precautions and warnings apply.

Ensure that all connections to the product are correct so as to avoid accidental risk of shock and/or fire, for example such as can arise from high voltage connected to low voltage terminals.

Follow the requirements of this manual, including adequate wiring size and type, terminal torque settings, voltage, current magnitudes applied, and adequate isolation/clearance in external wiring from high to low voltage circuits.

Use the device only for its intended purpose and application.

Ensure that all ground paths are uncompromised for safety purposes during device operation and service.

Ensure that the control power applied to the device, the AC current, and voltage input match the ratings specified on the relay nameplate. Do not apply current or voltage in excess of the specified limits.

Only qualified personnel are to operate the device. Such personnel must be thoroughly familiar with all safety cautions and warnings in this manual and with applicable country, regional, utility, and plant safety regulations.

Hazardous voltages can exist in the power supply and at the device connection to current transformers, voltage transformers, control, and test circuit terminals. Make sure all sources of such voltages are isolated prior to attempting work on the device.

Hazardous voltages can exist when opening the secondary circuits of live current transformers. Make sure that current transformer secondary circuits are shorted out before making or removing any connection to the current transformer (CT) input terminals of the device.

For tests with secondary test equipment, ensure that no other sources of voltages or currents are connected to such equipment and that trip and close commands to the circuit breakers or other switching apparatus are isolated, unless this is required by the test procedure and is specified by appropriate utility/plant procedure.

When the device is used to control primary equipment, such as circuit breakers, isolators, and other switching apparatus, all control circuits from the device to the primary equipment must be isolated while personnel are working on or around this primary equipment to prevent any inadvertent command from this device.

Use an external disconnect to isolate the mains voltage supply.

LED transmitters are classified as IEC 60825-1 Accessible Emission Limit (AEL) Class 1M. Class 1M devices are considered safe to the unaided eye. Do not view directly with optical instruments.

This product is rated to Class A emissions levels and is to be used in Utility, Substation Industrial environments. Not to be used near electronic devices rated for Class B levels.

1.2UR OVERVIEW 1.2.1 INTRODUCTION TO THE UR

Historically, substation protection, control, and metering functions were performed with electromechanical equipment. This equipment was gradually replaced by analog equipment, most of which emulated the single-function approach of their electromechanical precursors. Both technologies required expensive cabling and auxiliary equipment to produce functioning systems.

Recently, digital electronic equipment has begun to provide protection, control, and metering functions. Initially, this equipment was either single function or had very limited multifunction capability, and it did not significantly reduce the cabling and auxiliary equipment required. However, recent digital relays are multifunctional, reducing cabling and auxiliaries significantly. These devices also transfer data to central control facilities and software using electronic communications. The functions performed have become so broad that many users now prefer the term Intelligent Electronic Device (IED).

It is obvious to station designers that the amount of cabling and auxiliary equipment installed can be even further reduced, to 20% to 70% of levels common in 1990, and achieve large cost reductions. This requires placing even more functions within the IEDs.

Users of power equipment are also interested in reducing cost by improving power quality and personnel productivity, and in increasing system reliability and efficiency. These objectives are realized through software that is used to perform functions at both the station and supervisory levels. The use of these systems is growing rapidly.

High-speed communication is required to meet the data transfer rates required by modern automatic control and monitoring systems. Very high speed communications are required to perform protection signaling with a performance target response time for a command signal between two IEDs, from transmission to reception, of less than 3 milliseconds. This has been established by the IEC 61850 standard.

IEDs with such capabilities also provide significantly more power system data than was available, enhanced operations and maintenance, and permit the use of adaptive system configuration for protection and control systems. This new generation of equipment is easily incorporated into automation systems, at both the station and enterprise levels. The GE Multilin Universal Relay (UR) series meets these goals.

a) UR BASIC DESIGN

The UR is a digital-based device containing a central processing unit (CPU) that handles multiple types of input and output signals. The UR device can communicate over a local area network (LAN) with an operator interface, a programming device, or another UR device.

The CPU module contains firmware that provides protection elements in the form of logic algorithms, as well as programmable logic gates, timers, and latches for control features.

Protective elements

Read inputs

Solve logic

Set outputs

Input elements accept a variety of analog or digital signals from the field. The UR isolates and converts these signals into logic signals used by the relay.

Output elements convert and isolate the logic signals generated by the relay into digital or analog signals that can be used

to control field devices.

b) UR SIGNAL TYPES

The contact inputs and outputs are digital signals associated with connections to hard-wired contacts. Both ‘wet’ and ‘dry’ contacts are supported.

The virtual inputs and outputs are digital signals associated with UR-series internal logic signals. Virtual inputs include signals generated by the local user interface. The virtual outputs are outputs of FlexLogic™ equations used to customize the device. Virtual outputs can also serve as virtual inputs to FlexLogic equations.

The analog inputs and outputs are signals that are associated with transducers, such as Resistance Temperature Detec- tors (RTDs).

The CT and VT inputs refer to analog current transformer and voltage transformer signals used to monitor AC power lines. The UR-series relays support 1 A and 5 A CTs.

The remote inputs and outputs provide a means of sharing digital point state information between remote UR-series devices. The remote outputs interface to the remote inputs of other UR-series devices. Remote outputs are FlexLogic operands inserted into IEC 61850 GSSE and GOOSE messages.

The direct inputs and outputs provide a means of sharing digital point states between a number of UR-series IEDs over a dedicated fiber (single or multimode), RS422, or G.703 interface. No switching equipment is required as the IEDs are connected directly in a ring or redundant (dual) ring configuration. This feature is optimized for speed and intended for pilotaided schemes, distributed logic applications, or the extension of the input/output capabilities of a single relay chassis.

c) UR SCAN OPERATION

The UR-series devices operate in a cyclic scan fashion. The device reads the inputs into an input status table, solves the logic program (FlexLogic equation), and then sets each output to the appropriate state in an output status table. Any resulting task execution is priority interrupt-driven.

1 GETTING STARTED 1.2 UR OVERVIEW

1.2.3 SOFTWARE ARCHITECTURE

The firmware (software embedded in the relay) is designed in functional modules that can be installed in any relay as required. This is achieved with object-oriented design and programming (OOD/OOP) techniques.

Object-oriented techniques involve the use of objects and classes. An object is defined as “a logical entity that contains both data and code that manipulates that data”. A class is the generalized form of similar objects. By using this concept, one can create a protection class with the protection elements as objects of the class, such as time overcurrent, instantaneous overcurrent, current differential, undervoltage, overvoltage, underfrequency, and distance. These objects represent completely self-contained software modules. The same object-class concept can be used for metering, input/output control, software interface, communications, or any functional entity in the system.

Employing OOD/OOP in the software architecture of the T35 achieves the same features as the hardware architecture: modularity, scalability, and flexibility. The application software for any UR-series device (for example, feeder protection, transformer protection, distance protection) is constructed by combining objects from the various functional classes. This results in a common interface across the UR series.

1.2.4 IMPORTANT CONCEPTS

As described above, the architecture of the UR-series relays differ from previous devices. To achieve a general understanding of this device, some sections of Chapter 5 are quite helpful. The most important functions of the relay are contained in “elements”. A description of the UR-series elements can be found in the Introduction to elements section in chapter 5. Examples of simple elements, and some of the organization of this manual, can be found in the Control elements section of chapter 5. An explanation of the use of inputs from CTs and VTs is in the Introduction to AC sources section in chapter 5. A description of how digital signals are used and routed within the relay is contained in the Introduction to FlexLogic section in chapter 5.

1.4.2 COMMUNICATIONS

The EnerVista UR Setup software communicates to the relay via the faceplate RS232 port or the rear panel RS485 / Ethernet ports. To communicate via the faceplate RS232 port, a standard straight-through serial cable is used. The DB-9 male end is connected to the relay and the DB-9 or DB-25 female end is connected to the computer COM2 port as described in the CPU communications ports section of chapter 3.

Figure 1–7: RELAY COMMUNICATION OPTIONS

To communicate through the T35 rear RS485 port from a computer RS232 port, the GE Multilin RS232/RS485 converter box is required. This device (catalog number F485) connects to the computer using a straight-through serial cable. A shielded twisted-pair (20, 22, or 24 AWG) connects the F485 converter to the T35 rear communications port. The converter terminals (+, –, GND) are connected to the T35 communication module (+, –, COM) terminals. See the CPU communica- tions ports section in chapter 3 for details. The line is terminated with an R-C network (that is, 120 Ω, 1 nF) as described in the chapter 3.

All messages are displayed on a backlit liquid crystal display (LCD) to make them visible under poor lighting conditions. While the keypad and display are not actively being used, the display defaults to user-defined messages. Any high-priority event-driven message automatically overrides the default message and appears on the display.

It is recommended that passwords be set for each security level and assigned to specific personnel. There are two user security access levels, COMMAND and SETTING.

1. COMMAND

The COMMAND access level restricts the user from making any settings changes, but allows the user to perform the following operations:

• Change state of virtual inputs

• Clear event records

• Clear oscillography records

• Operate user-programmable pushbuttons

2. SETTING

The SETTING access level allows the user to make any changes to any of the setting values.

See the Changing Settings section in Chapter 4 for complete instructions on setting security-level passwords.

1.5.7 COMMISSIONING

Commissioning tests are included in the Commissioning chapter. The T35 requires minimal maintenance after it is commissioned into service. Since the T35 is a microprocessor-based

relay, its characteristics do not change over time. As such, no further functional tests are required. Expected service life is 20 years for UR devices manufactured June 2014 or later when applied in a controlled indoors environment and electrical conditions within specification.

The T35 performs a number of continual self-tests and takes the necessary action in case of any major errors (see the Relay Self-tests section in chapter 7). However, it is recommended that T35 maintenance be scheduled with other system maintenance. This maintenance can involve in-service, out-of-service, or unscheduled maintenance.

In-service maintenance:

1. Visual verification of the analog values integrity, such as voltage and current (in comparison to other devices on the corresponding system).

2. Visual verification of active alarms, relay display messages, and LED indications.

3. LED test.

4. Visual inspection for any damage, corrosion, dust, or loose wires.

5. Event recorder file download with further events analysis.

Out-of-service maintenance:

1. Check wiring connections for firmness.

2. Analog values (currents, voltages, RTDs, analog inputs) injection test and metering accuracy verification. Calibrated test equipment is required.

3. Protection elements setting verification (analog values injection or visual verification of setting file entries against relay settings schedule).

4. Contact inputs and outputs verification. This test can be conducted by direct change of state forcing or as part of the system functional testing.

5. Visual inspection for any damage, corrosion, or dust.

6. Event recorder file download with further events analysis.

7. LED Test and pushbutton continuity check.

Unscheduled maintenance, such as a disturbance causing system interruption:

1. View the event recorder and oscillography or fault report for correct operation of inputs, outputs, and elements.

If it is concluded that the relay or one of its modules is of concern, contact GE Multilin for service.

2 PRODUCT DESCRIPTION 2.1 INTRODUCTION

2 PRODUCT DESCRIPTION 2.1INTRODUCTION 2.1.1 OVERVIEW

The T35 Transformer Protection System is a microprocessor-based relay intended for protecting small, medium, and large three-phase power transformers involved in complicated power system configurations. The relay is available with two to six banks of three-phase inputs: either CTs or CTs and VTs.

Typical T35 applications include:

• Transformers with windings connected between two or more breakers.

• Transformers with windings without associated breakers, where the only available ones are those on buses, lines, or

feeders.

The percent and instantaneous differential elements are the primary protection elements. The backup protection elements, such as instantaneous overcurrent, can be expressed in fully configurable FlexElements™. The relay can also be configured to protect transformers with any phase shift between the windings and handle up to 32 times the ratio mismatch (see the phase and magnitude compensation descriptions in chapter 5).

Voltage, current, and power metering is built into the relay as a standard feature. Current parameters are available as total waveform RMS magnitude, or as fundamental frequency only RMS magnitude and angle (phasor).

Diagnostic features include an event recorder capable of storing 1024 time-tagged events, oscillography capable of storing up to 64 records with programmable trigger, content and sampling rate, and data logger acquisition of up to 16 channels, with programmable content and sampling rate. The internal clock used for time-tagging can be synchronized with an IRIGB signal, using the Simple Network Time Protocol (SNTP) over the Ethernet port, or using the Precision Time Protocol (PTP). This precise time stamping allows the sequence of events to be determined throughout the system. Events can also be programmed (via FlexLogic equations) to trigger oscillography data capture which may be set to record the measured parameters before and after the event for viewing on a personal computer (PC). These tools significantly reduce troubleshooting time and simplify report generation in the event of a system fault.

Several options are available for communication. A faceplate RS232 port can be used to connect to a computer for the programming of settings and the monitoring of actual values. The RS232 port has a fixed baud rate of 19.2 kbps. The rear RS485 port allows independent access by operating and engineering staff. It can be connected to system computers with baud rates up to 115.2 kbps. All serial ports use the Modbus RTU protocol. The 100Base-FX or 100Base-T Ethernet interface provides fast, reliable communications in noisy environments. The Ethernet port supports IEC 61850, Modbus/TCP, and TFTP protocols, PTP (according to IEEE Std. 1588-2008 or IEC 61588), and allows access to the relay via any standard web browser (T35 web pages). The IEC 60870-5-104 protocol is supported on the Ethernet port. DNP 3.0 and IEC 60870-5-104 cannot be enabled at the same time. The Ethernet port also supports the Parallel Redundancy Protocol (PRP) of IEC 62439-3 (clause 4, 2012) when purchased as an option.

Settings and actual values can be accessed from the front panel or EnerVista software. The T35 IEDs use flash memory technology that allows field upgrading as new features are added.

These power budgets are calculated from the manufacturer’s worst-case transmitter power and worst case receiver sensitivity.

The power budgets for the 1300 nm ELED are calculated from the manufacturer's transmitter power and receiver sensitivity at ambient temperature. At extreme temperatures these values deviate based on component tolerance. On average, the output power decreases as the temperature is increased by a factor 1dB / 5°C.

a) HORIZONTAL UNITS

The T35 Transformer Protection System is available as a 19-inch rack horizontal mount unit with a removable faceplate. The faceplate can be specified as either standard or enhanced at the time of ordering. The enhanced faceplate contains additional user-programmable pushbuttons and LED indicators.

The modular design allows the relay to be easily upgraded or repaired by a qualified service person. The faceplate is hinged to allow easy access to the removable modules, and is itself removable to allow mounting on doors with limited rear depth.

The case dimensions are shown below, along with panel cutout details for panel mounting. When planning the location of your panel cutout, ensure that provision is made for the faceplate to swing open without interference to or from adjacent equipment.

The relay must be mounted such that the faceplate sits semi-flush with the panel or switchgear door, allowing the operator access to the keypad and the RS232 communications port. The relay is secured to the panel with the use of four screws supplied with the relay.

3.1.2 REAR TERMINAL LAYOUT

The relay follows a convention with respect to terminal number assignments which are three characters long assigned in order by module slot position, row number, and column letter. Two-slot wide modules take their slot designation from the first slot position (nearest to CPU module) which is indicated by an arrow marker on the terminal block. See the following figure for an example of rear terminal assignments.

Figure 3–8: REAR TERMINAL VIEW

Do not touch any rear terminals while the relay is energized!

The small form-factor pluggable ports (SFPs) are pluggable transceivers. Do not use non-validated transceivers or install validated transceivers in the wrong Ethernet slot, else damage can occur.

Filter networks and transient protection clamps are used in the hardware to prevent damage caused by high peak voltage transients, radio frequency interference (RFI), and electromagnetic interference (EMI). These protective components can be damaged by application of the ANSI/IEEE C37.90 specified test voltage for a period longer than the specified one minute.

All Chassis 2000 V AC for 1 minute

3.2.3 CONTROL POWER

Control power supplied to the relay must be connected to the matching power supply range of the relay. If voltage is applied to the wrong terminals, damage can occur.

The T35 relay, like almost all electronic relays, contains electrolytic capacitors. These capacitors are well-known to deteriorate over time if voltage is not applied periodically. Deterioration can be avoided by powering up the relay at least once a year.

The power supply module can be ordered for two possible voltage ranges, and the UR can be ordered with or without a redundant power supply module option. Each range has a dedicated input connection for proper operation. The ranges are as shown below (see the Technical specifications section of chapter 2 for additional details):

• Low (LO) range: 24 to 48 V (DC only) nominal.

• High (HI) range: 125 to 250 V nominal. The power supply module provides power to the relay and supplies power for dry contact input connections. The power supply module provides 48 V DC power for dry contact input connections and a critical failure relay (see the

Typical wiring diagram earlier). The critical failure relay is a form-C device that is energized once control power is applied and the relay has successfully booted up with no critical self-test failures. If on-going self-test diagnostic checks detect a critical failure (see the Self-test errors section in chapter 7) or control power is lost, the relay is de-energize.

For high reliability systems, the T35 has a redundant option in which two T35 power supplies are placed in parallel on the bus. If one of the power supplies become faulted, the second power supply assumes the full load of the relay without any interruptions. Each power supply has a green LED on the front of the module to indicate it is functional. The critical fail relay of the module also indicates a faulted power supply.

3.2.4 CT/VT MODULES

A CT/VT module can have voltage or current inputs on channels 1 through 4 inclusive, or channels 5 through 8 inclusive. Channels 1 and 5 are intended for connection to phase A, and are labeled as such in the relay. Likewise, channels 2 and 6 are intended for connection to phase B, and channels 3 and 7 are intended for connection to phase C.

Channels 4 and 8 are intended for connection to a single-phase source. For voltage inputs, these channel are labelled as auxiliary voltage (VX). For current inputs, these channels are intended for connection to a CT between system neutral and ground, and are labelled as ground current (IG).

Verify that the connection made to the relay terminals for nominal current of 1 A or 5 A matches the secondary rating of the connected CTs. Unmatched CTs can result in equipment damage or inade-

quate protection. To connect the module, size 12 American Wire Gauge (AWG) is commonly used; the maximum size is 10 AWG. CT/VT modules can be ordered with a standard ground current input that is the same as the phase current input. Each AC

current input has an isolating transformer and an automatic shorting mechanism that shorts the input when the module is withdrawn from the chassis. There are no internal ground connections on the current inputs. Current transformers with 1 to 50000 A primaries and 1 A or 5 A secondaries can be used.

CT/VT modules with a sensitive ground input are also available. The ground CT input of the sensitive ground modules is 10 times more sensitive than the ground CT input of standard CT/VT modules. However, the phase CT inputs and phase VT inputs are the same as those of regular CT/VT modules.

The above modules have enhanced diagnostics that can automatically detect CT/VT hardware failure and take the relay out of service.

CT connections for both ABC and ACB phase rotations are identical as shown in the Typical wiring diagram. The exact placement of a zero-sequence core balance CT to detect ground fault current is shown as follows. Twisted-pair

cabling on the zero-sequence CT is recommended.

3.2.5 PROCESS BUS MODULES

The T35 can be ordered with a process bus interface module. This module is designed to interface with the GE Multilin HardFiber system, allowing bidirectional IEC 61850 fiber optic communications with up to eight HardFiber merging units, known as Bricks. The HardFiber system has been designed to integrate seamlessly with the existing UR-series applications, including protection functions, FlexLogic, metering, and communications.

The IEC 61850 process bus system offers the following benefits:

• Reduces labor associated with design, installation, and testing of protection and control applications using the T35 by

reducing the number of individual copper terminations

• Integrates seamlessly with existing T35 applications, since the IEC 61850 process bus interface module replaces the

traditional CT/VT modules

• Communicates using open standard IEC 61850 messaging

For additional details on the HardFiber system, see GE publication GEK-113658: HardFiber Process Bus System Instruction Manual.

3.2.6 CONTACT INPUTS AND OUTPUTS

Every contact input/output module has 24 terminal connections. They are arranged as three terminals per row, with eight rows in total. A given row of three terminals can be used for the outputs of one relay. For example, for form-C relay outputs, the terminals connect to the normally open (NO), normally closed (NC), and common contacts of the relay. For a form-A output, there are options of using current or voltage detection for feature supervision, depending on the module ordered. The terminal configuration for contact inputs is different for the two applications.

The contact inputs are grouped with a common return. The T35 has two versions of grouping: four inputs per common return and two inputs per common return. When a contact input/output module is ordered, four inputs per common is used. If the inputs must be isolated per row, then two inputs per common return should be selected (4D module).

The tables and diagrams on the following pages illustrate the module types (6A, etc.) and contact arrangements that can be ordered for the relay. Since an entire row is used for a single contact output, the name is assigned using the module slot position and row number. However, since there are two contact inputs per row, these names are assigned by module slot position, row number, and column position.

Some form-A / solid-state relay outputs include circuits to monitor the DC voltage across the output contact when it is open, and the DC current through the output contact when it is closed. Each of the monitors contains a level detector whose output is set to logic “On = 1” when the current in the circuit is above the threshold setting. The voltage monitor is set to “On = 1” when there is a voltage across open contact (the detector allows a current of about 1 to 2.5 mA), and the current monitor is set to “On = 1” when the current flowing through the closed contact exceeds about 80 to 100 mA. The voltage monitor is intended to check the health of the overall trip circuit, and the current monitor can be used to seal-in the output contact until an external contact has interrupted current flow. If enabled, the current monitoring can be used as a seal-in signal to ensure that the form-A contact does not attempt to break the energized inductive coil circuit and weld the output contacts.

Block diagrams are shown as follows for form-A and solid-state relay outputs with optional voltage monitor, optional current monitor, and with no monitoring. The actual values shown for contact output 1 are the same for all contact outputs. Form-A contact output with or without a current or voltage monitoring option is not polarity sensitive. The polarity shown in the figure is required for solid-state contact output connection.

Figure 3–14: FORM-A AND SOLID-STATE CONTACT OUTPUTS WITH VOLTAGE AND CURRENT MONITORING

The operation of voltage and current monitors is reflected with the corresponding FlexLogic operands (CONT OP # VON,

CONT OP # VOFF, and CONT OP # ION) which can be used in protection, control, and alarm logic. The typical application of

the voltage monitor is breaker trip circuit integrity monitoring; a typical application of the current monitor is seal-in of the control command.

Consider relay contacts unsafe to touch when the unit is energized.

USE OF FORM-A AND SOLID-STATE RELAY OUTPUTS IN HIGH IMPEDANCE CIRCUITS

For form-A and solid-state relay output contacts internally equipped with a voltage measuring circuit across the contact, the circuit has an impedance that can cause a problem when used in conjunction with external high input impedance monitoring equipment such as modern relay test set trigger circuits. These monitoring circuits may continue to read the form-A contact as being closed after it has closed and subsequently opened, when measured as an impedance.

The solution is to use the voltage measuring trigger input of the relay test set, and connect the form-A contact through a voltage-dropping resistor to a DC voltage source. If the 48 V DC output of the power supply is used as a source, a 500 Ω, 10 W resistor is appropriate. In this configuration, the voltage across either the form-A contact or the resistor can be used to monitor the state of the output.

Wherever a tilde “~” symbol appears, substitute with the slot position of the module; wherever a number sign “#” appears, substitute the contact number

When current monitoring is used to seal-in the form-A and solid-state relay contact outputs, the FlexLogic operand driving the contact output should be given a reset delay of 10 ms to prevent damage of the output contact (in situations when the element initiating the contact output is bouncing, at values in the region of the pickup value).

CONTACT INPUTS

A dry contact has one side connected to terminal B3b. This is the positive 48 V DC voltage rail supplied by the power supply module. The other side of the dry contact is connected to the required contact input terminal. Each contact input group has its own common (negative) terminal which must be connected to the DC negative terminal (B3a) of the power supply module. When a dry contact closes, a current of 1 to 3 mA flows through the associated circuit.

A wet contact has one side connected to the positive terminal of an external DC power supply. The other side of this contact is connected to the required contact input terminal. If a wet contact is used, then the negative side of the external source must be connected to the relay common (negative) terminal of each contact group. The maximum external source voltage for this arrangement is 300 V DC.

The voltage threshold at which each group of four contact inputs detects a closed contact input is programmable as 17 V DC for 24 V sources, 33 V DC for 48 V sources, 84 V DC for 110 to 125 V sources, and 166 V DC for 250 V sources.

There is no provision in the relay to detect a DC ground fault on 48 V DC control power external output. We recommend using an external DC supply.

USE OF CONTACT INPUTS WITH AUTO-BURNISHING

The contact inputs sense a change of the state of the external device contact based on the measured current. When external devices are located in a harsh industrial environment (either outdoor or indoor), their contacts can be exposed to various types of contamination. Normally, there is a thin film of insulating sulfidation, oxidation, or contaminates on the surface of the contacts, sometimes making it difficult or impossible to detect a change of the state. This film must be removed to establish circuit continuity – an impulse of higher than normal current can accomplish this.

The contact inputs with auto-burnish create a high current impulse when the threshold is reached to burn off this oxidation layer as a maintenance to the contacts. Afterwards the contact input current is reduced to a steady-state current. The impulse has a 5 second delay after a contact input changes state.

Figure 3–18: CURRENT THROUGH CONTACT INPUTS WITH AUTO-BURNISHING

Regular contact inputs limit current to less than 3 mA to reduce station battery burden. In contrast, contact inputs with autoburnishing allow currents up to 50 to 70 mA at the first instance when the change of state was sensed. Then, within 25 to 50 ms, this current is slowly reduced to 3 mA as indicated above. The 50 to 70 mA peak current burns any film on the contacts, allowing for proper sensing of state changes. If the external device contact is bouncing, the auto-burnishing starts when external device contact bouncing is over.

Another important difference between the auto-burnishing input module and the regular input modules is that only two contact inputs have common ground, as opposed to four contact inputs sharing one common ground (refer to the Contact Input and Output Module Wiring diagrams). This is beneficial when connecting contact inputs to separate voltage sources. Consequently, the threshold voltage setting is also defined per group of two contact inputs.

The auto-burnish feature can be disabled or enabled using the DIP switches found on each daughter card. There is a DIP switch for each contact, for a total of 16 inputs.

3.2.7 TRANSDUCER INPUTS AND OUTPUTS

Transducer input modules can receive input signals from external DCmA output transducers (DCmA In) or resistance temperature detectors (RTDs). Hardware and software are provided to receive signals from these external transducers and convert these signals into a digital format for use as required.

Transducer output modules provide DC current outputs in several standard DCmA ranges. Software is provided to configure virtually any analog quantity used in the relay to drive the analog outputs.

Every transducer input/output module has a total of 24 terminal connections. These connections are arranged as three terminals per row with a total of eight rows. A given row can be used for either inputs or outputs, with terminals in column "a" having positive polarity and terminals in column "c" having negative polarity. Since an entire row is used for a single input/ output channel, the name of the channel is assigned using the module slot position and row number.

Each module also requires that a connection from an external ground bus be made to terminal 8b. The current outputs require a twisted-pair shielded cable, where the shield is grounded at one end only. The following figure illustrates the transducer module types (5A, 5C, 5D, 5E, and 5F) and channel arrangements that can be ordered for the relay.

Wherever a tilde “~” symbol appears, substitute with the slot position of the module.

b) RS485 PORTS

RS485 data transmission and reception are accomplished over a single twisted pair with transmit and receive data alternating over the same two wires. Through the use of the port, continuous monitoring and control from a remote computer, SCADA system, or PLC is possible.

To minimize errors from noise, the use of shielded twisted pair wire is recommended. Correct polarity must also be observed. For instance, the relays must be connected with all RS485 “+” terminals connected together, and all RS485 “–” terminals connected together. Though data is transmitted over a two-wire twisted pair, all RS485 devices require a shared reference, or common voltage. This common voltage is implied to be a power supply common. Some systems allow the shield (drain wire) to be used as common wire and to connect directly to the T35 COM terminal (#3); others function correctly only if the common wire is connected to the T35 COM terminal, but insulated from the shield.

To avoid loop currents, ground the shield at only one point. If other system considerations require the shield to be grounded at more than one point, install resistors (typically 100 ohms) between the shield and ground at each grounding point. Each relay needs to be daisy-chained to the next one in the link. A maximum of 32 relays can be connected in this manner without exceeding driver capability. For larger systems, additional serial channels must be added. It is also possible to use commercially available repeaters to have more than 32 relays on a single channel. Avoid star or stub connections entirely.

Lightning strikes and ground surge currents can cause large momentary voltage differences between remote ends of the communication link. For this reason, surge protection devices are internally provided at both communication ports. An isolated power supply with an optocoupled data interface also acts to reduce noise coupling. To ensure maximum reliability, all equipment should have similar transient protection devices installed.

3.3DIRECT INPUT/OUTPUT COMMUNICATIONS 3.3.1 DESCRIPTION

The direct inputs and outputs feature makes use of the type 7 series of communications modules, which allow direct messaging between UR devices. These communications modules are outlined in the table later in this section.

The communications channels are normally connected in a ring configuration as shown in the following figure. The transmitter of one module is connected to the receiver of the next module. The transmitter of this second module is then connected to the receiver of the next module in the ring. This is continued to form a communications ring. The figure illustrates a ring of four UR-series relays with the following connections: UR1-Tx to UR2-Rx, UR2-Tx to UR3-Rx, UR3-Tx to UR4-Rx, and UR4-Tx to UR1-Rx. A maximum of 16 UR-series relays can be connected in a single ring

Figure 3–26: DIRECT INPUT AND OUTPUT SINGLE CHANNEL CONNECTION

The interconnection for dual-channel type 7 communications modules is shown as follows. Two channel modules allow for a redundant ring configuration. That is, two rings can be created to provide an additional independent data path. The required connections are: UR1-Tx1 to UR2-Rx1, UR2-Tx1 to UR3-Rx1, UR3-Tx1 to UR4-Rx1, and UR4-Tx1 to UR1-Rx1 for the first ring; and UR1-Tx2 to UR4-Rx2, UR4-Tx2 to UR3-Rx2, UR3-Tx2 to UR2-Rx2, and UR2-Tx2 to UR1-Rx2 for the second ring.

Figure 3–27: DIRECT INPUT AND OUTPUT DUAL CHANNEL CONNECTION

The following diagram shows the connection for three UR-series relays using two independent communication channels. UR1 and UR3 have single type 7 communication modules; UR2 has a dual-channel module. The two communication channels can be of different types, depending on the type 7 modules used. To allow the direct input and output data to cross- over from channel 1 to channel 2 on UR2, the

DIRECT I/O CHANNEL CROSSOVER setting should be “Enabled” on UR2. This

forces UR2 to forward messages received on Rx1 out Tx2, and messages received on Rx2 out Tx1.

3.3.4 G.703 INTERFACE

a) DESCRIPTION

The following figure shows the 64K ITU G.703 co-directional interface configuration.

The G.703 module is fixed at 64 kbps. The SETTINGS > PRODUCT SETUP > DIRECT I/O > DIRECT I/O DATA RATE setting is not applicable to this module.

AWG 24 twisted shielded pair is recommended for external connections, with the shield grounded only at one end. Connecting the shield to pin X1a or X6a grounds the shield since these pins are internally connected to ground. Thus, if pin X1a or X6a is used to ground the shield at one end, do not ground the shield at the other end. This interface module is protected by surge suppression devices.

Figure 3–31: G.703 INTERFACE CONFIGURATION

The following figure shows the typical pin interconnection between two G.703 interfaces. For the actual physical arrangement of these pins, see the Rear terminal assignments section earlier in this chapter. All pin interconnections are to be maintained for a connection to a multiplexer.

Figure 3–32: TYPICAL PIN INTERCONNECTION BETWEEN TWO G.703 INTERFACES

Pin nomenclature can differ from one manufacturer to another. Therefore, it is not uncommon to see pinouts numbered TxA, TxB, RxA and RxB. In such cases, it can be assumed that “A” is equivalent to “+” and “B” is equivalent to “–”.

b) G.703 SELECTION SWITCH PROCEDURES

1. With the power to the relay off, remove the G.703 module (7R or 7S) as follows. Record the original location of the module to help ensure that the same or replacement module is inserted into the correct slot.

2. Simultaneously pull the ejector/inserter clips located at the top and at the bottom of each module in order to release the module for removal.

3. Remove the module cover screw.

4. Remove the top cover by sliding it towards the rear and then lift it upwards.

5. Set the timing selection switches (channel 1, channel 2) to the desired timing modes.

6. Replace the top cover and the cover screw.

The ejector/inserter clips located at the top and at the bottom of each module must be in the disengaged position as the module is smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips simultaneously. When the clips have locked into position, the module is fully inserted.

If octet timing is enabled (ON), this 8 kHz signal is asserted during the violation of bit 8 (LSB) necessary for connecting to higher order systems. When T35s are connected back-to-back, octet timing is disabled (OFF).

d) G.703 TIMING MODES

There are two timing modes for the G.703 module: internal timing mode and loop timing mode (default).

• Internal Timing Mode: The system clock is generated internally. Therefore, the G.703 timing selection should be in the internal timing mode for back-to-back (UR-to-UR) connections. For back-to-back connections, set for octet timing (S1 = OFF) and timing mode to internal timing (S5 = ON and S6 = OFF).

• Loop Timing Mode: The system clock is derived from the received line signal. Therefore, the G.703 timing selection should be in loop timing mode for connections to higher order systems. For connection to a higher order system (URto-multiplexer, factory defaults), set to octet timing (S1 = ON) and set timing mode to loop timing (S5 = OFF and S6 = OFF).

The switch settings for the internal and loop timing modes are shown below:

e) G.703 TEST MODES

In minimum remote loopback mode, the multiplexer is enabled to return the data from the external interface without any processing to assist in diagnosing G.703 line-side problems irrespective of clock rate. Data enters from the G.703 inputs, passes through the data stabilization latch which also restores the proper signal polarity, passes through the multiplexer and then returns to the transmitter. The differential received data is processed and passed to the G.703 transmitter module after which point the data is discarded. The G.703 receiver module is fully functional and continues to process data and passes it to the differential Manchester transmitter module. Since timing is returned as it is received, the timing source is expected to be from the G.703 line side of the interface.

In dual loopback mode, the multiplexers are active and the functions of the circuit are divided into two with each receiver/ transmitter pair linked together to deconstruct and then reconstruct their respective signals. Differential Manchester data enters the Differential Manchester receiver module and then is returned to the differential Manchester transmitter module. Likewise, G.703 data enters the G.703 receiver module and is passed through to the G.703 transmitter module to be returned as G.703 data. Because of the complete split in the communications path and because, in each case, the clocks are extracted and reconstructed with the outgoing data, in this mode there must be two independent sources of timing. One source lies on the G.703 line side of the interface while the other lies on the differential Manchester side of the interface.

3.3.5 RS422 INTERFACE

a) DESCRIPTION

There are two RS422 inter-relay communications modules available: single-channel RS422 (module 7T) and dual-channel RS422 (module 7W). The modules can be configured to run at 64 kbps or 128 kbps. AWG 20-24 twisted shielded pair cable is recommended for external connections. These modules are protected by optically-isolated surge suppression devices.

The shield pins (6a and 7b) are internally connected to the ground pin (8a). Proper shield termination is as follows:

• Site 1: Terminate shield to pins 6a or 7b or both.

• Site 2: Terminate shield to COM pin 2b.

Match the clock terminating impedance with the impedance of the line.

The following figure shows the typical pin interconnection between two single-channel RS422 interfaces installed in slot W. All pin interconnections are to be maintained for a connection to a multiplexer.

b) TWO-CHANNEL APPLICATION VIA MULTIPLEXERS

The RS422 interface can be used for single channel or two channel applications over SONET/SDH or multiplexed systems. When used in single-channel applications, the RS422 interface links to higher order systems in a typical fashion observing transmit (Tx), receive (Rx), and send timing (ST) connections. However, when used in two-channel applications, certain criteria must be followed since there is one clock input for the two RS422 channels. The system functions correctly when the following connections are observed and your data module has a terminal timing feature. Terminal timing is a common feature to most synchronous data units that allows the module to accept timing from an external source. Using the terminal timing feature, two channel applications can be achieved if these connections are followed: The send timing outputs from the multiplexer (data module 1), connects to the clock inputs of the UR–RS422 interface in the usual fashion. In addition, the send timing outputs of data module 1 is also paralleled to the terminal timing inputs of data module 2. By using this configuration, the timing for both data modules and both UR–RS422 channels are derived from a single clock source. As a result, data sampling for both of the UR–RS422 channels is synchronized via the send timing leads on data module 1 as shown below. If the terminal timing feature is not available or this type of connection is not desired, the G.703 interface is a viable option that does not impose timing restrictions.

Figure 3–38: TIMING CONFIGURATION FOR RS422 TWO-CHANNEL, 3-TERMINAL APPLICATION

Data module 1 provides timing to the T35 RS422 interface via the ST(A) and ST(B) outputs. Data module 1 also provides timing to data module 2 TT(A) and TT(B) inputs via the ST(A) and AT(B) outputs. The data module pin numbers have been omitted in the figure above since they vary by manufacturer.

c) TRANSMIT TIMING

The RS422 interface accepts one clock input for transmit timing. It is important that the rising edge of the 64 kHz transmit timing clock of the multiplexer interface is sampling the data in the center of the transmit data window. Therefore, it is important to confirm clock and data transitions to ensure proper system operation. For example, the following figure shows the positive edge of the Tx clock in the center of the Tx data bit.

d) RECEIVE TIMING

The RS422 interface utilizes NRZI-MARK modulation code and; therefore, does not rely on an Rx clock to recapture data. NRZI-MARK is an edge-type, invertible, self-clocking code.

To recover the Rx clock from the data-stream, an integrated DPLL (digital phase lock loop) circuit is utilized. The DPLL is driven by an internal clock, which is 16-times over-sampled, and uses this clock along with the data-stream to generate a data clock that can be used as the SCC (serial communication controller) receive clock.

The following figure shows the combined RS422 plus fiberoptic interface configuration at 64K baud. The 7L, 7M, 7N, 7P, and 74 modules are used in two-terminal with a redundant channel or three-terminal configurations where channel 1 is employed via the RS422 interface (possibly with a multiplexer) and channel 2 via direct fiber.

AWG 20-24 twisted shielded pair is recommended for external RS422 connections and ground the shield only at one end. For the direct fiber channel, address power budget issues properly.

When using a LASER Interface, attenuators can be necessary to ensure that you do not exceed

maximum optical input power to the receiver.

3.3.8 IEEE C37.94 INTERFACE

The UR-series IEEE C37.94 communication modules (modules types 2G, 2H, 76, and 77) are designed to interface with IEEE C37.94 compliant digital multiplexers or an IEEE C37.94 compliant interface converter for use with direct input and output applications. The IEEE C37.94 standard defines a point-to-point optical link for synchronous data between a multiplexer and a teleprotection device. This data is typically 64 kbps, but the standard provides for speeds up to 64n kbps, where n = 1, 2,…, 12. The UR-series C37.94 communication modules are either 64 kbps (with n fixed at 1) for 128 kbps (with n fixed at 2). The frame is a valid International Telecommunications Union (ITU-T) recommended G.704 pattern from the standpoint of framing and data rate. The frame is 256 bits and is repeated at a frame rate of 8000 Hz, with a resultant bit rate of 2048 kbps.

The specifications for the module are as follows:.

• IEEE standard: C37.94 for 1 × 128 kbps optical fiber interface (for 2G and 2H modules) or C37.94 for 2 × 64 kbps optical fiber interface (for 76 and 77 modules)

• Fiber optic cable type: 50 nm or 62.5 µm core diameter optical fiber

• Fiber optic mode: multi-mode

• Fiber optic cable length: up to 2 km

• Fiber optic connector: type ST

• Wavelength: 820 ±40 nm

• Connection: as per all fiber optic connections, a Tx to Rx connection is required

The UR-series C37.94 communication module can be connected directly to any compliant digital multiplexer that supports the IEEE C37.94 standard as shown below.

The UR-series C37.94 communication module can be connected to the electrical interface (G.703, RS422, or X.21) of a non-compliant digital multiplexer via an optical-to-electrical interface converter that supports the IEEE C37.94 standard, as shown below.

In 2008, GE Digital Energy released revised modules 76 and 77 for C37.94 communication to enable multi-ended fault location functionality with firmware 5.60 release and higher. All modules 76 and 77 shipped since the change support this feature and are fully backward compatible with firmware releases below 5.60. For customers using firmware release 5.60 and higher, the module can be identified with "Rev D" printed on the module and is to be used on all ends of T35 communication for two and three terminal applications. Failure to use it at all ends results in intermittent communication alarms. For customers using firmware revisions below 5.60, it is not required to match the revision of the modules installed.

Internal timing mode

Loop timing mode

(factory default)

The UR-series C37.94 communication module has six switches that are used to set the clock configuration. The functions of these control switches are shown below.

For the internal timing mode, the system clock is generated internally. Therefore, the timing switch selection should be internal timing for relay 1 and loop timed for relay 2. There must be only one timing source configured.

For the looped timing mode, the system clock is derived from the received line signal. Therefore, the timing selection should be in loop timing mode for connections to higher order systems.

The IEEE C37.94 communications module cover removal procedure is as follows:

1. With power to the relay off, remove the IEEE C37.94 module (type 2G, 2H, 76 or 77 module) as follows. Record the original location of the module to help ensure that the same or replacement module is inserted into the correct slot.

2. Simultaneously pull the ejector/inserter clips located at the top and at the bottom of each module in order to release the module for removal.

3. Remove the module cover screw.

4. Remove the top cover by sliding it towards the rear and then lift it upwards.

5. Set the timing selection switches (channel 1, channel 2) to the desired timing modes (see description above).

6. Replace the top cover and the cover screw.

7. Re-insert the IEEE C37.94 module. Take care to ensure that the correct module type is inserted into the correct slot position. The ejector/inserter clips located at the top and at the bottom of each module must be in the disengaged position as the module is smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips simultaneously. When the clips have locked into position, the module is fully inserted.

The UR-series C37.94SM communication modules (2A and 2B) are designed to interface with modified IEEE C37.94 compliant digital multiplexers or IEEE C37.94 compliant interface converters that have been converted from 820 nm multi-mode fiber optics to 1300 nm ELED single-mode fiber optics. The IEEE C37.94 standard defines a point-to-point optical link for synchronous data between a multiplexer and a teleprotection device. This data is typically 64 kbps, but the standard provides for speeds up to 64n kbps, where n = 1, 2,…, 12. The UR-series C37.94SM communication module is 64 kbps only with n fixed at 1. The frame is a valid International Telecommunications Union (ITU-T) recommended G.704 pattern from the standpoint of framing and data rate. The frame is 256 bits and is repeated at a frame rate of 8000 Hz, with a resultant bit rate of 2048 kbps.

The specifications for the module are as follows:

• Emulated IEEE standard: emulates C37.94 for 1 × 64 kbps optical fiber interface (modules set to n = 1 or 64 kbps)

• Fiber optic mode: single-mode, ELED compatible with HP HFBR-1315T transmitter and HP HFBR-2316T receiver

• Fiber optic cable length: up to 11.4 km

• Fiber optic connector: type ST

• Connection: as per all fiber optic connections, a Tx to Rx connection is required The UR-series C37.94SM communication module can be connected directly to any compliant digital multiplexer that sup-

ports C37.94SM as shown below.

It can also can be connected directly to any other UR-series relay with a C37.94SM module as shown below.

4 HUMAN INTERFACES 4.1ENERVISTA UR SETUP SOFTWARE INTERFACE 4.1.1 INTRODUCTION

The EnerVista UR Setup software provides a graphical user interface (GUI) as one of two human interfaces to a UR device. The alternate human interface is implemented via the device’s faceplate keypad and display (see the Faceplate interface section in this chapter).

The EnerVista UR Setup software provides a single facility to configure, monitor, maintain, and troubleshoot the operation of relay functions, connected over local or wide area communication networks. It can be used while disconnected (offline) or connected (online) to a UR device. In offline mode, settings files can be created for eventual downloading to the device. In online mode, you can communicate with the device in real-time.

The EnerVista UR Setup software is provided with every T35 relay and runs on Microsoft and XP. This chapter provides a summary of the basic EnerVista UR Setup software interface features. The EnerVista UR Setup Help File provides details for getting started and using the EnerVista UR Setup software interface.

To start using the EnerVista UR Setup software, site and device definition are required. See the EnerVista UR Setup Help File or refer to the Connecting EnerVista UR Setup with the T35 section in Chapter 1 for details.

4.1.2 CREATING A SITE LIST

4.1.3 ENERVISTA UR SETUP OVERVIEW

a) ENGAGING A DEVICE

The EnerVista UR Setup software can be used in online mode (relay connected) to directly communicate with the T35 relay. Communicating relays are organized and grouped by communication interfaces and into sites. Sites can contain any number of relays selected from the UR-series of relays.

b) USING SETTINGS FILES

The EnerVista UR Setup software interface supports three ways of handling changes to relay settings:

• In offline mode (relay disconnected) to create or edit relay settings files for later download to communicating relays

• While connected to a communicating relay to directly modify any relay settings via relay data view windows, and then

save the settings to the relay

• You can create/edit settings files and then write them to the relay while the interface is connected to the relay Settings files are organized on the basis of file names assigned by the user. A settings file contains data pertaining to the

following types of relay settings:

• Device definition

• Product setup

• System setup

• FlexLogic

• Grouped elements

• Control elements

• Inputs/outputs

• Testing Factory default values are supplied and can be restored after any changes. The following communications settings are not transferred to the T35 with settings files.

When a settings file is loaded to a T35 that is in-service, the following sequence occurs:

1. The T35 takes itself out of service.

2. The T35 issues a

3. The T35 closes the critical fail contact.

c) CREATING AND EDITING FLEXLOGIC

You create or edit a FlexLogic equation in order to customize the relay. You can subsequently view the automatically generated logic diagram.

d) VIEWING ACTUAL VALUES

You can view real-time relay data such as input/output status and measured parameters.

UNIT NOT PROGRAMMED major self-test error.

e) VIEWING TRIGGERED EVENTS

While the interface is in either online or offline mode, you can view and analyze data generated by triggered specified parameters, via one of the following:

• Event recorder

The event recorder captures contextual data associated with the last 1024 events, listed in chronological order from most recent to oldest.

• Oscillography

The oscillography waveform traces and digital states are used to provide a visual display of power system and relay operation data captured during specific triggered events.

f) FILE SUPPORT

• Execution: Any EnerVista UR Setup file that is opened launches the application or provides focus to the already opened application. If the file was a settings file (has a URS extension) that had been removed from the Settings List tree menu, it is added back to the Settings List tree menu.

• Drag and Drop: The Site List and Settings List control bar windows are each mutually a drag source and a drop target for device-order-code-compatible files or individual menu items. Also, the Settings List control bar window and any Windows Explorer directory folder are each mutually a file drag source and drop target.

New files that are dropped into the Settings List window are added to the tree, which is automatically sorted alphabetically with respect to settings file names. Files or individual menu items that are dropped in the selected device menu in the Site List window are automatically sent to the online communicating device.

g) FIRMWARE UPGRADES

The firmware of a T35 device can be upgraded, locally or remotely, via the EnerVista UR Setup software. The corresponding instructions are provided by the EnerVista UR Setup Help file under the topic “Upgrading Firmware”.

If you are upgrading from version 7.0 or 7.1 to 7.2 or later, some CPU modules require a new boot version. Update this first in EnerVista under Maintenance > Update Firmware.

NOTE

Before backing up settings and upgrading, set the Settings > Product Setup > Security > Dual Permission Security Access > Remote Setting Authorized and Local Setting Authorized settings to "ON." Otherwise, the upgrade is blocked

and results in an "Unable to put relay in flash mode" message.

Modbus addresses assigned to firmware modules, features, settings, and corresponding data items (that is, default values, minimum/maximum values, data type, and item size) can change slightly from version to version of firmware. The addresses are rearranged when new features are added or existing features are enhanced or modified.

EEPROM DATA ERROR message displayed after upgrading/downgrading the firmware is a resettable, self-test

The message intended to inform users that the Modbus addresses have changed with the upgraded firmware. This message does not signal any problems when appearing after firmware upgrades.

4.2EXTENDED ENERVISTA UR SETUP FEATURES 4.2.1 SETTINGS TEMPLATES

Setting file templates simplify the configuration and commissioning of multiple relays that protect similar assets. An example of this is a substation that has ten similar feeders protected by ten UR-series F60 relays.

In these situations, typically 90% or greater of the settings are identical between all devices. The templates feature allows engineers to configure and test these common settings, then lock them so that they are not available to users. For example, these locked down settings can be hidden from view for field engineers, allowing them to quickly identify and concentrate on the specific settings.

The remaining settings (typically 10% or less) can be specified as editable and be made available to field engineers installing the devices. These are settings such as protection element pickup values and CT and VT ratios.

The settings template mode allows the user to define which settings are visible in EnerVista UR Setup. Settings templates can be applied to both settings files (settings file templates) and online devices (online settings templates). The functionality is identical for both purposes.

a) ENABLING THE SETTINGS TEMPLATE

The settings file template feature is disabled by default. The following procedure describes how to enable the settings template for UR-series settings files.

1. Select a settings file from the offline window of the EnerVista UR Setup main screen.

2. Right-click the selected device or settings file and select the Template Mode > Create Template option. The settings file template is now enabled and the file tree displayed in light blue. The settings file is now in template editing

mode. Alternatively, the settings template can also be applied to online settings. The following procedure describes this process.

1. Select an installed device from the online window of the EnerVista UR Setup main screen.

2. Right-click the selected device and select the Template Mode > Create Template option.

The software prompts for a template password. This password is required to use the template feature and must be at least four characters in length.

3. Enter and re-enter the new password, then click OK to continue. The online settings template is now enabled. The device is now in template editing mode.

b) EDITING THE SETTINGS TEMPLATE

The settings template editing feature allows the user to specify which settings are available for viewing and modification in EnerVista UR Setup. By default, all settings except the FlexLogic equation editor settings are locked.

1. Select an installed device or a settings file from the tree menu on the left of the EnerVista UR Setup main screen.

2. Select the Template Mode > Edit Template option to place the device in template editing mode.

3. Enter the template password then click OK.

4. Open the relevant settings windows that contain settings to be specified as viewable.

5. Specify the settings to make viewable by clicking them.

The setting available to view is displayed against a yellow background as shown below.

Figure 4–3: SETTINGS TEMPLATE VIEW, TWO SETTINGS SPECIFIED AS EDITABLE

6. Click on Save to save changes to the settings template.

7. Proceed through the settings tree to specify all viewable settings.

c) ADDING PASSWORD PROTECTION TO A TEMPLATE

It is highly recommended that templates be saved with password protection to maximize security. The following procedure describes how to add password protection to a settings file template.

1. Select a settings file from the offline window on the left of the EnerVista UR Setup main screen.

2. Selecting the Template Mode > Password Protect Template option.

The software prompts for a template password. This password must be at least four characters in length.

3. Enter and re-enter the new password, then click OK to continue. The settings file template is now secured with password protection.

When templates are created for online settings, the password is added during the initial template creation step. It does not need to be added after the template is created.

d) VIEWING THE SETTINGS TEMPLATE

Once all necessary settings are specified for viewing, users are able to view the settings template on the online device or settings file. There are two ways to specify the settings view with the settings template feature:

• Display only those settings available for editing

• Display all settings, with settings not available for editing greyed-out Use the following procedure to only display settings available for editing:

1. Select an installed device or a settings file from the tree menu on the left of the EnerVista UR Setup main screen.

2. Apply the template by selecting the Template Mode > View In Template Mode option.

3. Enter the template password then click OK to apply the template. Once the template has been applied, users are limited to view and edit the settings specified by the template. The effect of

applying the template to the phase time overcurrent settings is shown below.
