339 Motor Protection System

Chapter 1: Introduction

Introduction

Overview

The 339 Motor Protection System is a microprocessor based relay providing suitable protection of medium voltage motors. The small footprint and the withdrawable option make the relay ideal for panel mounting on either new or retrofit installations. The combination of proven hardware, a variety of protection and control features, and communications, makes the relay ideal for total motor protection and control. Equipped with serial (RS485), USB, and Ethernet ports, and a wide selection of protocols such as Modbus, DNP3.0, IEC 60870-5-103, 60870-5-104, GOOSE, the relay is the best-in-class for MCCs, SCADA and inter-relay communications. The relay provides excellent transparency with respect to power system conditions and events, through its four-line 20-character display, as well as the EnerVista SR3 Setup program. Conveniently located LEDs provide indication of overall relay operation, as well as alarm, pickup, and motor status.

The relay provides the following key benefits:

• Withdrawable small footprint – saves on rewiring and space.

• Fast setup (Quick Setup) menu provided, to guide users through a wide range of motor

• Large four-line LCD display, LEDs, and an easy-to-navigate keypad.

• Multiple communication protocols for simultaneous access when integrated into

management applications.

CHAPTER 1: INTRODUCTION DESCRIPTION OF THE 339 MOTOR PROTECTION SYSTEM

Description of the 339 Motor Protection System

CPU

Relay functions are controlled by two processors: a Freescale MPC5554 32-bit microprocessor measures all analog signals and digital inputs and controls all output relays; a Freescale MPC520B 32-bit microprocessor controls all the Ethernet communication protocols.

Analog Input Waveform Capture

Magnetic transformers are used to scale-down the incoming analog signals from the source instrument transformers. The analog signals are then passed through a 960 Hz low pass anti-aliasing filter. All signals are then simultaneously captured by sample and hold buffers to ensure there are no phase shifts. The signals are converted to digital values by a 12-bit A/D converter before finally being passed on to the CPU for analysis.

Both current and voltage are sampled thirty-two times per power frequency cycle. These ‘raw’ samples are scaled in software, then placed into the waveform capture buffer, thus emulating a fault recorder. The waveforms can be retrieved from the relay via the EnerVista SR3 Setup software for display and diagnostics.

Frequency

Frequency measurement is accomplished by measuring the time between zero crossings of the Bus VT phase A voltage . The signals are passed through a low pass filter to prevent false zero crossings. Sampling is synchronized to the Va-x voltage zero crossing which results in better co-ordination for multiple relays on the same bus.

Phasors, Transients, and Harmonics

Current waveforms are processed twice every cycle with a DC Offset Filter and a Discrete Fourier Transform (DFT). The resulting phasors have fault current transients and all harmonics removed. This results in a motor that is extremely secure and reliable; one that will not overreach.

Processing of AC Current Inputs

The DC Offset Filter is an infinite impulse response (IIR) digital filter, which removes the DC component from the asymmetrical current present at the moment a fault occurs. This is done for all current signals used for overcurrent protection; voltage signals bypass the DC Offset Filter. This filter ensures no overreach of the overcurrent protection.

The Discrete Fourier Transform (DFT) uses exactly one sample cycle to calculate a phasor quantity which represents the signal at the fundamental frequency; all harmonic components are removed. All subsequent calculations (e.g. RMS, power, etc.) are based upon the current and voltage phasors, such that the resulting values have no harmonic components.

Protection Elements

All protection elements are processed twice every cycle to determine if a pickup has occurred or a timer has expired. The protection elements use RMS current/voltage, based on the magnitude of the phasor. Hence, protection is impervious to both harmonics and DC transients.

RMIO module installation

The optional remote module (RMIO) is designed to be mounted near the motor. This eliminates the need for multiple RTD cables to run back from the motor, which may be in a remote location, to the switchgear. Although the RMIO is internally shielded to minimize noise pickup and interference, it should be mounted away from high current conductors or sources of strong magnetic fields.

CHAPTER 2: INSTALLATION ELECTRICAL INSTALLATION

CAUTION

Phase sequence and transformer polarity

For correct operation of the relay features, the user must follow the instrument transformer polarities, shown in the Typical Wiring Diagram. Note the solid square markings shown with all instrument transformer connections. When the connections adhere to this drawing, the arrow shows the direction of power flow for positive watts and the positive direction of lagging vars. The phase sequence is user programmable for either ABC or ACB rotation.

Phase current inputs

The relay has three (3) channels for phase current inputs, each with an isolating transformer. There are no internal ground connections on the current inputs. Current transformers with 30 to 1500 A primaries may be used.

CAUTION:

Verify that the relay’s nominal input current of 1 A or 5 A matches the secondary rating of the connected CTs. Unmatched CTs may result in equipment damage or inadequate protection.

CAUTION:

Before working on CTs, they MUST be short circuited.

Ground and CBCT inputs

The 339 has two isolating transformers with separate terminals for the 1A/5A secondary and the CBCT (50:0.025). Only one ground terminal type can be used at a time. There are no internal ground connections on the ground current inputs.

The maximum ground CT primary for the 1 A and 5 A taps is 1500 A. Alternatively the sensitive ground input, 50:0.025, can be used to detect ground current on high resistance grounded systems.

The ground CT connection can either be a zero sequence (core balance) installation or a residual connection. Note that only 1 A and 5 A secondary CTs may be used for the residual connection. A typical residual connection is illustrated below. The zero-sequence connection is shown in the typical wiring diagram. The zero-sequence connection is recommended. Unequal saturation of CTs, CT mismatch, size and location of motor, resistance of the power system, motor core saturation density, etc. may cause false readings in the residually connected ground fault circuit.

NOTE

CAUTION

NOTE

Voltage inputs

The relay has three channels for AC voltage inputs, each with an isolating transformer. Voltage transformers up to a maximum 300:1 ratio may be used. The nominal secondary voltage must be in the 50 to 240 V range. The three phase inputs are designated as the “bus voltage”. The Bus VT connections most commonly used, wye and delta (or open delta), are shown in the typical wiring diagram.

NOTE:

If Delta VTs are used, the zero sequence voltage (V0) will be zero. Also, with the Delta VT connection, the phase-neutral voltage cannot be measured and will not be displayed.

NOTE:

CAUTION:

NOTE:

The relay can be applied to both metering and protection feeders with up to 20000 V phase-to-phase voltage. Please ensure that the selected VT ratio and VT secondary do not result in a primary voltage exceeding 20000 V.

Control power

Control power supplied to the relay must match the installed power supply range. If the applied voltage does not match, damage to the unit may occur. All grounds MUST be connected for safe, normal operation regardless of control power supply type.

The label found on the relay specifies its order code or model number. The installed power supply’s operating range will be one of the following:

LO: 24 to 48 V DC (Nominal Range: 20 to 60 V DC) HI: 125 to 250 V DC/120 to 240 V AC (Nominal Range: 84 to 250 V DC/60 to 300 V AC)

The relay chassis ground terminals should be connected directly to the ground bus, using the shortest practical path. A tinned copper, braided, shielding and bonding cable should be used. As a minimum, 96 strands of number 34 AWG should be used. Belden catalog number 8660 is suitable.

Isolate power prior to servicing.

An external switch, circuit breaker, or other protective device must be connected close to the equipment.

External contacts can be connected to the relay’s ten (10) digital inputs. These contacts are wet only.

The inputs can be programmed to different thresholds depending on the DC voltage (17, 33, 84, 166).

CAUTION:

Ensure correct polarity on contact input connections and do not connect any contact input circuits to ground or else relay hardware may be damaged.

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. In addition, the negative side of the external source must be connected to the relay’s DC negative rail at Terminal C11. The maximum external source voltage for this arrangement is 300 V DC.

Trip and Close output relays

The relay is equipped with seven electromechanical output relays: 2 Form A (Relay 1, Relay

2–16 339 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL

2), and 5 Form C (Relays 3 to 7). When SWITCHING DEVICE is selected as BREAKER: Output Relays:

• For special purpose: – Output Relay 1 (non-failsafe, seal-in): Breaker Trip – Output Relay 2 (non-failsafe, seal-in): Breaker Close – Output Relay 3 (non-failsafe, self-reset): Start Inhibit – Output Relay 7 (fail-safe, self-reset): Critical Failure

• For general purpose: – Output Relays 4 to 6 - non-failsafe; can be programmed as self-reset or latched.

Operation of the Trip and Close output relays is designed to be controlled by the state of the circuit breaker as monitored by a 52a or 52b contact.

• The Trip and Close relays reset after the breaker is detected in a state corresponding to the command. When a relay feature sends a command to one of these special relays, it will remain operational until the requested change of breaker state is confirmed by a breaker auxiliary contact and the initiating condition has reset .

• If the initiating feature resets, but the breaker does not change state, the output relay will be reset after a default interval of 2 seconds.

• If neither of the breaker auxiliary contacts, 52a nor 52b, is programmed to a contact input, the Trip Relay is de-energized after either the delay programmed in the Breaker Failure feature, or a default interval of 100 ms after the initiating input resets. The Close Relay is de-energized after 200 ms.

• If a delay is programmed for the Trip or Close contact seal-in time, then this delay is added to the reset time. Note that the default setting for the seal-in time is 40 ms.

expires (if the Breaker Failure element is enabled), or 100 ms after the feature causing the trip resets. Close Relay operates for 200 ms.

Breaker monitoring (Trip and Close coil monitoring) is performed by a built-in voltage monitor on Form A output relays: #1 Trip, and #2 Close. The voltage monitor is connected across each of the two Form A contacts, and the relay effectively detects healthy current through the circuit. In order to do this, an external jumper must be connected between terminals A2 and A3 for Trip coil monitoring, or/and B4, and B5 for Close coil monitoring.

As long as the current through the Voltage Monitor is above the threshold of the trickle currents (see Technical Specification for Form A output relays), the circuit integrity for the Trip (Close) coil is effectively normal. If the Trip (Close) coil circuit gets disconnected, or if in general a high resistance is detected in the circuitry, a Trip (Close) alarm will be set and the “ALARM” and “MAINTENANCE” LEDs will be on provided the corresponding Coil Monitor feature is enabled.

Example: The figures below show the two different connections of the breaker trip (close) coil to the relay’s trip output #1 terminals (close output #2 terminals) for both no voltage monitoring and voltage monitoring of the trip (close) circuit integrity.

To ensure that all devices in a daisy-chain are at the same potential, it is imperative that the common terminals of each RS485 port are tied together and grounded only once, at the master or at the slave. Failure to do so may result in intermittent or failed communications.

The source computer/PLC/SCADA system should have similar transient protection devices installed, either internally or externally. Ground the shield at one point only, as shown in the figure above, to avoid ground loops.

Correct polarity is also essential. The IEDs must be wired with all the positive (+) terminals connected together and all the negative (–) terminals connected together. Each relay must be daisy-chained to the next one. Avoid star or stub connected configurations. The last device at each end of the daisy-chain should be terminated with a 120 ohm ¼ watt resistor in series with a 1 nF capacitor across the positive and negative terminals. Observing these guidelines will ensure a reliable communication system immune to system transients.

IRIG-B

IRIG-B is a standard time code format that allows time stamping of events to be synchronized among connected devices within 1 millisecond. The IRIG time code formats are serial, width-modulated codes which can be either DC level shift or amplitude modulated (AM) form. The type of form is auto-detected by the relay. Third party equipment is available for generating the IRIG-B signal; this equipment may use a GPS satellite system to obtain the time reference so that devices at different geographic locations can also be synchronized.

Display

The 80-character liquid crystal display (LCD) allows visibility under varied lighting conditions. When the keypad and display are not being used, system information is displayed after a user-defined period of inactivity. Pressing the Menu key during the display of the default message returns the display to the last message shown before the default message appeared. Any trip, alarm, or pickup is displayed immediately, automatically overriding the default message.

Working with the

Keypad

The display messages are organized into a Main Menu, pages, and sub-pages. There are four main menus labeled Actual Values, Quick Setup, Setpoints, and Maintenance. Pressing the MENU key followed by the MESSAGE key scrolls through the four Main Menu headers, which appear in sequence as follows:

Figure 2: The four Main Menu headers

Pressing the MESSAGE ► key or the ENTER key from these Main Menu pages will display the corresponding menu Page. Use the MESSAGE ▲ and MESSAGE ▼ keys to scroll through the Page headers.

Figure 3: Typical paging operation from Main Menu selection

339 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 3–3

FRONT CONTROL PANEL INTERFACE CHAPTER 3: INTERFACES

When the display shows SETPOINTS, pressing the MESSAGE ► key or the ENTER key will display the page headers of programmable parameters (referred to as setpoints in the manual). When the display shows ACTUAL VALUES, pressing the MESSAGE ► key or the ENTER key displays the page headers of measured parameters (referred to as actual values in the manual).

Each page is broken down further into logical sub-pages of messages. The MESSAGE ▲ and MESSAGE ▼ keys are used to navigate through the sub-pages. A summary of the setpoints and actual values pages can be found in the Chapters : Setpoints and Actual Values, respectively.

The ENTER key is dual purpose. It is used to enter the sub-pages and to store altered setpoint values into memory to complete the change. The MESSAGE ► key can also be used to enter sub-pages but not to store altered setpoints.

The ESCAPE key or the MESSAGE key can be used to exit the sub-pages. The VALUE keys are used to scroll through the possible choices of an enumerated setpoint.

They also decrement and increment numerical setpoints. The RESET key resets any latched conditions that are not currently active. This includes

resetting latched output relays, latched Trip LEDs, breaker operation failure, and trip / close coil failures.

The MESSAGE ▲ and MESSAGE ▼ keys scroll through any active conditions in the relay. Diagnostic messages are displayed indicating the state of protection and monitoring elements that are picked up, operating, or latched.

Self-test errors The relay performs self diagnostics at initialization (after power up), and continuously as a

background task to ensure that the hardware and software are functioning correctly. There are two types of self-test warnings indicating either a minor or major problem. Minor problems indicate a problem with the relay that does not compromise protection of the power system. Major errors indicate a problem with the relay which takes it out of service.

CAUTION:

Self-Test Warnings may indicate a serious problem with the relay hardware!

Upon detection of a minor problem, the relay will:

• Turn on the "TROUBLE" LED at the same time as the "IN SERVICE" LED is on.

• Display the error on the relay display.

• Record the minor self-test error in the Event Recorder. Upon detection of a major problem, the relay will:

• De-energize critical failure relay (Output Relay 7).

• Inhibit operation of all other output relays (1 to 6).

• Turn off the "IN SERVICE" LED.

• Turn on the "TROUBLE" LED.

•Flash the "ALARM" LED.

• Display the cause of major self-test failure.

SOFTWARE SETUP CHAPTER 3: INTERFACES

Password security Password security is an optional feature of the which can be setup using the SR3 EnerVista

Setup software. The password system has been designed to facilitate a hierarchy for centralized management. This is accomplished through a Master level access password which can be used for resetting lower level access passwords and higher level privileged operations. In cases where operational security is required as well as a central administrative authority then the use of the password system is highly encouraged. The feature robustness of this system requires it to be managed exclusively through the EnerVista setup software. This section describes how to perform the initial setup. For more details on the password security feature, refer to Chapter 6 - Password Security.

3–34 339 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL

Page 77

CHAPTER 3: INTERFACES SOFTWARE SETUP

1. 339 devices shipped from the factory are initially set with security disabled. If the

password security feature is to be used, the user must first change the Master Reset Password from the initial Null setting, this can only be done over communications, not from the front panel keypad. The new Master Reset Password must be 8 to 10 characters in length, and must have minimum 2 letters and 2 numbers. The letters are case sensitive. After entering a valid Master Reset Password, enter the new Master Reset Password again to confirm, then select Change Password.

2. Now that the Master Reset Password has been programmed, enter it again to log in to

the Master Access level. The Master Level permits setup of the Remote and Local Passwords. If the Master Reset Password has been lost, record the Encrypted Key and contact the factory to have it decrypted.

3. With Master Level access, the user may disable password security altogether, or

change the Master Reset Password.

4. The Master Access level allows programming of the Remote Setpoint and Remote

Control passwords. These passwords are initially set to a Null value, and can only be set or changed from a remote user over RS485 or Ethernet communications. Remote Passwords must be 3 to 10 characters in length.

5. Initial setup of the Local Setpoint and Local Control passwords requires the Master

Access level. If Overwrite Local Passwords is set to YES, Local passwords can be changed remotely only (over RS485 or Ethernet). If Overwrite Local Passwords is set to

339 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 3–35

Page 78

SOFTWARE SETUP CHAPTER 3: INTERFACES

NO, Local passwords can be changed locally only (over USB or keypad). If changing Local Passwords is permitted locally, the keypad user can only change the Local Passwords if they have been changed from the initial NULL value to a valid one. Local Passwords must be 3 to 10 characters in length.

6. If any Remote password has never been set, that level will not be attainable except when logged in as the Master Level. The same logic applies to the Local passwords.

7. When passwords have been set, the user will be prompted to enter the appropriate password depending on the interface being used (remote or local), and the nature of the change being made (setpoint or control). If the correct password is entered, the user is now logged into that access level over that interface only. The access level turns off after a period of 5 minutes of inactivity, if control power is cycled, or if the user enters an incorrect password.

A1 STATUS CHAPTER 4: ACTUAL VALUES

Motor status

MOTOR STATUS

Range: Tripped, Stopped, Starting, Running, Overload

The motor status is tripped following any protection trip operation or lockout. After all protection trips and lockout have cleared, the tripped motor status can be reset from the front panel reset key, by closure of the reset or lockout reset contact input, or via communications. The emergency restart function also resets tripped status.

When the motor status is stopped, detection of phase current above the FLA changes the status to starting. Running status follows starting when the current then drops below FLA. Running status continues as long as phase current greater than 5% of CT is detected. To accommodate applications where current does not rise above the thermal overload pickup setting on start, running status is also declared when the contact inputs indicate the motor is online. When phase current falls below 5% of CT the status changes to stopped. To accommodate applications where motor idle current is less than 5% CT, a further requirement to change status to stopped is that the contact inputs do not indicate the motor is online.

For single speed applications, an enabled 52a contact input closed or an enabled 52b contact input open is taken as indication of motor online. If both are enabled, the relay assumes the motor is online if the 52a contact is closed and the 52b contact is open.

For two speed applications, closure either of the High Speed Switch contact input or of the Low Speed Switch contact input is indication of motor online. If either 52a or 52b contact input is enabled, a further requirement is that these indicate the breaker is closed.

Use of these contact inputs (52a Contact, 52b Contact, High Speed Switch, Low Speed Switch) for motor online detection is optional, but is recommended to ensure proper detection of motor running, especially in cases where the starting current is less than the thermal overload pickup setting or motor idle current is less than 5% of CT.

The relay measures all RMS currents and voltages, frequency, and RTD inputs. Other values like neutral current, symmetrical components, power factor, power (real, reactive, apparent), are derived. All quantities are recalculated every power system cycle and perform protection and monitoring functions. Displayed metered quantities are updated approximately three (3) times a second for readability. All phasors and symmetrical components are referenced to the A-N voltage phasor for wye-connected VTs; to the A-B voltage phasor for delta connected VTs; or to the phase A current phasor when no voltage signals are present.

Event records

The 339 has an event recorder which runs continuously. All event records are stored in memory such that information is maintained for up to 3 days even after losing relay control power. The events are displayed from newest to oldest event. Each event has a header message containing a summary of the event that occurred, and is assigned an event number equal to the number of events that have occured since the recorder was cleared. The event number is incremented for each new event.

The Event Recorder captures and stores the last 256 events. All events are stored in nonvolatile memory where the information is maintained, even in the case where relay control power is lost.

Shown below is an example of an event record caused by a Breaker Open operation, and the recorded information at the time of this record.
