Testing and Troubleshooting

Commissioning Tests

Arc-Flash Protection 
Tests

Follow the procedures described in 

Section 2: Installation

 to complete the 

installation of the Arc-Flash Detection (AFD) fiber-optic sensors in the 
switchgear equipment to be protected. Make sure the switchgear doors, 
panels, etc., are closed and in the final operating configuration. This will 
assure that the ambient light as measured by the sensors is indicative of the 
normal operating condition. DO NOT ENERGIZE the switchgear for the 
commissioning tests described below. The relay must have the application 
settings as required, be energized, and in the ENABLED state. 

Arc-Flash Detection (AFD) System Continuous Self-Testing

The SEL-751A relay continuously tests (periodic) and monitors all four arc-
flash sensor subsystems and reports the status. The test period is constant, set 
to 10 minutes.

1. Point-Sensor AFD Self-Test

Each point-sensor AFD subsystem on the relay has a Transmit 
LED channel and a Light Detector channel. The LED 
periodically sends a light pulse through the transmit fiber cable, 
which is "coupled" into the receive fiber cable in the point 
sensor. The light travels back to the light detector on the relay. 
The light measurement by the detector is used to determine the 
integrity of the point-sensor AFD loop and report PASS/FAIL 
status.

2. Bare-Fiber Sensor AFD Self-Test

The bare-fiber sensor is basically a loop, starting from the 
Transmit LED and returning to the Light Detector. The relay 
self-test involves sending a light pulse around the loop and 
measuring the light received at the detector. The light 
measurement by the detector is used to determine the integrity 
of the Bare-Fiber Sensor AFD loop and report PASS/FAIL 
status.

METER LIGHT Report

Use the serial port ASCII command 

METER

 

L

 and view the METER LIGHT 

report as shown in 

Figure 5.11

.

The report shows the light intensity measurements in percent of full scale (%) 
for the four AFD channels. This  measurement represents the "background" or 
the "ambient" light in the switchgear areas being monitored for arc-flash. This 
measurement is used in determining the "Time-Over Light" TOL1 to TOL4 
settings for arc-flash protection (refer to 

Section 4: Protection and Logic 

Functions

 for details). If there is excessive background light (any of the relay 

word bits AFSnEL picks up) or if there is a diagnostic failure (any of the relay
