2. General

The Eaton Arc Flash Relay 101 (EAFR-101) is a sophisticated micro-processor based arc flash protection relay including complete self-supervision functionality. It is designed to minimize the damage caused by an arcing fault (arc flash) by sensing light from the point sensor and tripping the circuit breaker sourcing the fault current. The EAFR-101 complete system self-supervision function provides the highest level of dependability by continuously monitoring all internal system functions along with external connections.

The EAFR-101 is designed according to the latest protection relay standards and is therefore suitable for installations in rough environments, such as utility, traditional or renewable power plants, off shore, marine, oil and gas, mining, steel, or any other heavy industry applications. It is also well suited for commercial and institutional electrical systems.

3. Operation and Configuration

3.1 LED Indicator Functions

TThe EAFR-101 contains 11 indication LEDs. A user definable text pocket can be slid in under the label for identifying each LED function (except Power and Error LEDs). LEDs are located at the front plate of the relay for clear viewing without a need for opening doors.

During power up, the relay performs a LED test. All LEDs are turned on for two seconds and then off. Only the blue

Power LED will remain ON. After powered up, the relay goes into protection mode in 50 ms even while the LED test is being performed. During normal operation only the blue power LED is ON.

The point sensor LEDs are off during the inactive condition. If a point arc sensor is activated, the corresponding sensor channel LED will turn on if the activation is longer than 1.5 ms. The sensor LED activation function is latched

(steady light). To clear the LED, the “Set” button should be pressed.

In case of a loose sensor wire or configuration mismatch

(new sensor attached without running auto-configuration system setup [see Section 3.3.1) situation, the corresponding LED for that point sensor will start flashing and the Error

LED will activate.

The Binary I/O LEDs are indicating the I/O-line status. If any of the lines become active for more than 1.5 ms, the corresponding LED will turn on (latch).

In a trip situation, the corresponding trip LED will turn on.

Trip outputs are controlled by the dipswitch settings (see

Section 3.5).

All activation and trip indication LEDs are latched, even if the dipswitch setting is in the non-latched mode. They have to be cleared by pushing the “Set” button.

LED indications are stored in non-volatile EPROM memory for identifying the trip information in case the auxiliary power is lost. When re-powering the relay after power supply loss, the actual LED status can be visualized from the front of the relay.

3.3 Push-button Description

The EAFR-101 contains one single push-button (SET) that can be used for all operational functions of the relay. The push-button is used to initialize the auto-configuration of the system (see Section 3.3.1) and for resetting the indicators and latched output relays.

3.4 Reset

All LED indications and latched trip relays are reset by pressing the “SET” button for one second. Otherwise, the latched trip relays will remain activated until auxiliary power is disconnected. All LED indications will remain active until reset is performed by the operator, even when auxiliary power supply is disconnected (see Section 3.6: Non-volatile

Memory).

3.3.1 Auto Configuration (System Setup)

When all sensors and binary lines have been connected, an auto-configuration procedure must be executed. The initialization sequence is performed by pressing the “Set” button for two seconds. The EAFR-101 sensor LEDs and BI1/BI2

LEDs start blinking. The relay scans these inputs to see if they are connected and when an input is detected, the corresponding LEDs are illuminated to mark that a connection was found. The inputs without connection continue blinking during the remaining three seconds. After five seconds, all LEDs are turned off. During this system setup, the dipswitch setting are also stored in non-volatile memory.

All sensor inputs will remain operational even when they are not auto-configured. The auto-configuration is only used for self-supervision purposes.

N otee:

To redo auto-configuration for a relay containing less connections (binary inputs/outputs or sensors) than in a previously memorized set-up, a dip-switch (anyone) must be moved back and forth prior to performing auto-configuration. The timeout allowing a new configuration is one minute. Reconfiguration with more connections is allowed without moving a dipswitch.

Figure 4. EAFR-101 Dipswitch SW1 and EAFR-101D Dipswitch SW1.

3.5 Dipswitch Settings

EAFR-101 functionality, such as tripping logic, is configured using dipswitch settings. Different trip configurations can be easily programmed by selecting the appropriate dipswitch positions. This gives users the flexibility to change settings dependent on the application. Tripping may be selected based on arc light only or arc light and current thresholds (or other tripping criteria such as under-voltage, or similar). Current threshold or other tripping criteria may be applied to binary input BI1 for blocking a trip caused by natural light sources. Also, the CBFP configuration may be enabled using the dipswitches. Dipswitches are located at the back of the relay for easy access (see Figure 4: EAFR-

101 Dipswitch SW1 and Table 2: EAFR-101 Dipswitch Setting

Selection for details of settings).

3.6 Non-volatile Memory

All critical system data, including dipswitch settings and auto-configuration file described in Section 3.3.1, are stored in EPROM non-volatile memory to ensure correct operation and full self-supervision, even if auxiliary power is temporarily lost.

Also, all LED indications described in Section 3.1 are stored in non-volatile memory in order to provide quick recovery of the system status indication, even if auxiliary power is temporarily lost. This feature is especially important if auxiliary power is lost after tripping.

Non-volatile memory does not require a power supply to maintain information and will retain settings and indications permanently without power.

4. Arc Sensors

The EAFR-101 relay series provides the use of point arc light sensors to be utilized in different switchgear types, according to the specific application requirements. Arc light point sensors are typically installed in metal clad compartments, providing quick accurate location of the faulted area.

4.1.1 EAFR-01 Installation and Wiring

The EAFR-01 point sensor can be installed either on or through the compartment wall. An example of on the wall mounting is seen in Figure 8. The EAFR-01 is fixed against the wall using two screws. The same screw pattern is utilized in a through wall mounting arrangement. In this arrangement the unit is turned around and the point of the eye of the photodiode sensor protrudes through a small hole cut in the wall. The point of the sensor now faces the compartment to be protected. This allows for the body of the sensor and cabling to be located outside the compartment. For both types of installation, two screws are attached from the back side of the sensor. No external mounting plates are needed.

Figure 8. EAFR-01 Point Sensor Mounted to the

Compartment Wall.

4.1 Arc Light Point Sensor EAFR-01

The EAFR-01 is an arc light point sensor with a light sensitive photodiode element activated by receiving arc light.

The EAFR-01 arc sensors should be mounted in the switchgear cubicles in such a way that the light sensitive part can receive light from the protected area. Typically, one sensor per closed metal clad compartment is used. In open spaces, such as the busbar section, arc sensors should be mounted at a maximum of two meters (6.56 ft) apart.

The fixed light sensitivity of the EAFR-01-A sensor is 8000

Lux. The sensor does not require any user settings. The point sensor’s light detection radius is 180 degrees. Other point sensors are available with different Lux sensitivities,

EAFR-01-B at 25,000 Lux and EAFR-01-C at 50,000 Lux.

Figure 7. EAFR-01 Arc Light Point Sensor.

The cable to be used for wiring to the sensor should be a shielded, twisted pair cable. Table 5 lists several cables that can be used. Equivalent cable styles are acceptable to be used for the dielectric and temperature requirements of the application. Cable connectors are located beneath the covers that can be conveniently detached for fastening the sensor wires. The cover will be attached after installing the wires. Cable connectors are located at both ends of the sensor for series connecting a maximum of three sensors in one line (see Figure 9).

5. System Self-supervision


If a sensor failure occurs, the relay will go into the ERROR mode. The ERROR LED will turn on, the SF relay will deenergize, and the corresponding faulty sensor channel LED will start blinking. In this situation, the relay is still in protection mode, but with the faulty sensor channel blocked. If the error is resolved, the relay will automatically clear the

SF-status. This means that the SF relay will energize and the ERROR LED will turn off. If one or more of the sensors are disconnected, the healthy sensors remain in use and the relay remains operational. The EAFR-101 will remain in Error mode until the disconnected sensors are repaired.

If a dipswitch setting is changed after the auto-configuration function (see Section 3.3.1: Auto Configuration) has been executed, the relay will go into SF alarm mode. The configured (stored) setting is however still valid and the relay is still operational.

9. A maximum amount of three arc sensors can be daisychained to the same sensor input on the EAFR-101 relay (see Figure 18).


6. Application Examples

The EAFR-101 may be applied to a variety of power switchgear and control gear layouts and technologies. Some typical applications are described in this section. Please consult your nearest Eaton representative for a solution to your particular application.

The Auto Configuration is a part of the Self Supervision

Function which ensures that all connections and sensors are fully functional and ready to operate at all times.

5. System Self-supervision

The EAFR-101 includes an extensive self-supervision feature. Self-supervision includes both internal functions and external connections. The self-supervision module monitors power supply, hardware and software malfunctions, and binary input connection and sensor problems. Dipswitch settings are also supervised by comparing the actual value with stored non-volatile memory data (see Section 3.3.1:

Auto Configuration [System Setup]).

In a healthy condition, the POWER LED is on and the

System Failure (SF) relay is energized. If the self-supervision function detects a faulty condition or the power supply fails, the self-supervision relay is released and the ERROR

LED is illuminated.

6.1 MV or LV Application with Current and Light

Condition

The EAFR-101 may be applied requiring both over-current and arc light conditions for trip. In this application, tripping is performed only if both conditions are fulfilled simultaneously. Typically, the over-current condition is obtained from an EAFR-110 relay and the trip relay will be activated in 7 ms. The over-current condition may also be monitored by non-Eaton products (e.g.: generic feeder protection relay) and the total operation time is then dependent on device feeding the over-current signal to the EAFR-101.

The sensor channel S1 can be set to operate on arc light only, even if other channels operate on both conditions of arc light and over-current.

Figure 19 shows an example of a system applying both over-current and arc light for tripping from the sensor channels S2, S3, and S4 activations and arc light only from sensor channel S1 activation. The S1 channel is monitoring the transformer feeder bus duct above the current monitoring point. a maximum three arc light point sensors type EAFR-

01 can be connected to each sensor channel.

The current monitoring signal is in this application coming from an external over-current relay.

6.2 Wind Power Application Example (Light Only

Condition)

The EAFR-101 may be applied using arc light only as the tripping criteria.

The example in Figure 20 shows a typical wind power scheme where a permanent magnet synchronous generator (PMSG) is applied with a converter cabinet and LV/MV transformer.

The EAFR-101 is equipped with four point sensor channels and each channel may have up to three sensors (type

EAFR01) connected in series allowing for up to 12 point sensors. In this application, three sensor channels with three sensors in each channel are utilized. In the event of arc light in any of the compartments containing a sensor, the EAFR-

101 relay will execute a trip to all three circuit breakers in

7 ms thus clearing the arc fault in total time of 7 ms + CB opening time. Additionally, an electronic lock-out relay (T3) is utilized to provide the lock-out function ensuring the fault is recognized and corrected prior to putting the generator back into service (safety loop).

6.3 Circuit Breaker Failure Protection (CBFP)

The EAFR-101 includes a selective circuit breaker failure function which can be enabled by dipswitch setting (see

Section 3.5: Dipswitch Settings). When enabled, the breaker failure function activates when the tripped breaker fails to operate. The breaker failure function is activated if the

EAFR-101 detects the presence of light after a set operating time. When EAFR-101 is set to operate on light and current, both parameters must persist to activate CBFP. Breaker failure can be set to operate either on 100 ms or 150 ms delay

(Section 3.5: Dipswitch Settings).

7. Connections

7.1 Outputs

7.1.1 Trip Relays T1 and T2

The EAFR-101 relay has integrated trip relays T1 and T2 for tripping of the circuit breakers. The T1 and T2 relays are normally open type (NO).

7.1.2 Trip Relays T3 and T4

The T3 relay output may act either as an electronic lock-out relay or as a trip relay. This option must be specified when ordering. When the T3 is factory configured as electronic lock-out relay, it is normally open type (NO) and will hold its position until manual reset command or until auxiliary power supply is lost. When re-applying the auxiliary power supply, the electronic lock-out relay will return to the contact condition prior to loosing the auxiliary power. This NC relay output can be used for tripping contactor controlled devices.

Alternately, the T3 relay can be ordered as normally closed

(NC) type relay EAFR-101B, EAFR-101DB.

The T3 relay follows the operation of T1 and activates whenever T1 is activated.

Trip relay T4 is a common trip relay that operates anytime the T1 or T2 relay operates and can be used either for tripping one more disconnecting device or for trip alarm to local or remote monitoring and alarming system.

For details on sensors, refer to Section 4: Arc Sensors.

7.3 Auxiliary Voltage

The auxiliary power supply voltage is (110-220) Vac / (125-

7.2.2 Binary Inputs BI1 and BI2

The EAFR-101 contains two binary inputs. The BI1 is always reserved for second trip criteria signal. In the most typical application, the EAFR-101 is receiving over-current information from the Eaton EAFR-110 device. Over-current information may come also from a non-Eaton device (e.g.: an upstream protection relay). Alternately, any other signal

(such as under-voltage, or similar) can be used as second trip criteria along with light information.

23.5 (0.93)

10. Testing

It is recommended that the EAFR-101 relay be tested prior to substation energizing. Testing is carried out by simulating arc light to each sensor and verifying the tripping and LED indication. For arc light simulation, a superior camera flash type is used: Canon Speedlite

®

430EX or equivalent. For testing of non-latched signals and the CBFP function, use a Mini Maglite

®

2 Cell AAA or equivalent type of flashlight.

Check that the camera flash or flashlight has fully charged battery(ies) when testing.

10.1 Carrying Out Testing in the Light Only Mode

1. Check that the dipswitch setting positions are in accordance to your application.

2. Activate the camera flash within 20 cm (7.87 in.) of the

EAFR-01 to be used.

3. Verify that the corresponding sensor channel indication

LED status is changed to ON.

4. Verify the relay output(s) activation(s) by checking the circuit breaker status or by monitoring trip contact status. The circuit breaker should open or contacts operate.

N otee:

A best practice is to operate the circuit breaker during testing.

5. Verify that the corresponding relay output(s) LED(s) indication status is changed to ON.

6. If the binary output (BO1) signal is utilized, verify the

BO1 signal activation by the status change of the relevant input where the binary output signal is connected, or by measuring the signal output voltage.

N otee:

The BO1 signal is a non-latched type.

7. If a binary output signal is utilized, verify that the BO1

LED is illuminated.

8. Press the SET push-button to reset all indications and latches.

9. If a binary input BI2 is utilized as master trip to activate the corresponding binary input, verify that the trip has occurred by repeating Steps 4 and 5.


11. Repeat the testing procedure for all sensors.

14. If the binary input BI2 is utilized for master trip to activate the BI2, verify that a trip has occurred by repeating

Steps 4 and 5.


16. Repeat the testing procedure for all sensors.

10.3 Testing the CBFP Function

The circuit breaker failure function is tested by leaving light signal and second trip criteria signal (e.g. over-current), if applicable, active for above the set CBFP time of either 100 or 150 ms. The trip relay T2 and binary output BO1 should be active after the set time delay.

10.4 Testing the Arc Flash Protection Unit Operation

Time

The EAFR-101 operation time test is not required at commissioning as it is performed by Eaton as a type test and routine production test. Refer to the routine test reports sent with EAFR-101 relay and consult your nearest Eaton representative for type test reports.

However, if it is deemed necessary, a site timing test may be conducted using the following instructions.

1. Use a calibrated relay test set.

2. Connect an output from the relay test set to the camera flash (Metz

®

20B1 or equivalent input) for initializing the flash and configure a relay test set timer to be started simultaneously with flash.

3. Connect the EAFR-101 trip output T1, T2, T3, or T4 to the relay test set input and configure the input to stop the timer.

4. Place camera flash to a maximum 20 cm (8 in.) distance of the EAFR-01 or EAFR fiber sensor.

5. Initiate the flash and timer using the relay test set output.

6. Read the measured time between simulated arc and trip contact operation.

7. Subtract the digital input delay of the relay test set from the final measured time if applicable. For specific test instructions consult the manufacturer of the relay test set.
