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.

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.
1
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.

Display messages are organized into pages under the following headings: actual values, settings, commands, and targets.
The MENU key navigates through these pages. Each heading page is divided further into logical subgroups.
The MESSAGE keys navigate through the subgroups. The VALUE keys increment or decrement numerical setting values
when in programming mode. These keys also scroll through alphanumeric values in the text edit mode. Alternatively, values can be entered with the numeric keypad.
The decimal key initiates and advances to the next character in text edit mode or enters a decimal point.
The HELP key can be pressed at any time for context-sensitive help messages.
The ENTER key stores altered setting values.
1.5.2 MENU NAVIGATION
Press the MENU key to select a header display page (top-level menu). The header title appears momentarily followed by a
header display page menu item. Each press of the MENU key advances through the following main heading pages:
• Actual values
• Settings
• Commands
• Targets
• User displays (when enabled)
1.5.3 MENU HIERARCHY
The setting and actual value messages are arranged hierarchically. The header display pages are indicated by double
scroll bar characters (), while sub-header pages are indicated by single scroll bar characters (). The header display
pages represent the highest level of the hierarchy and the sub-header display pages fall below this level. The MESSAGE
UP and DOWN keys move within a group of headers, sub-headers, setting values, or actual values. Continually pressing
the MESSAGE RIGHT key from a header display displays specific information for the header category. Conversely, continually pressing the MESSAGE LEFT key from a setting value or actual value display returns to the header display.

SYSTEM SETUP
The relay is in the default “Not Programmed” state when it leaves the factory. When powered up successfully, the Trouble
LED is on and the In Service LED off. The relay in the “Not Programmed” state blocks signaling of any output relay. These
conditions remain until the relay is explicitly put in the “Programmed” state.

NOTE
The settings for the relay can be programmed manually (see Chapter 5) via the faceplate keypad or remotely via the
EnerVista UR Setup software (see the EnerVista UR Setup help file).
1.5.5 RELAY PASSWORDS
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.
1.5.6 FLEXLOGIC CUSTOMIZATION

FlexLogic equation editing is required for setting user-defined logic for customizing the relay operations. See the FlexLogic
section in Chapter 5.

1.5.7 COMMISSIONING
1
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.
