If it is concluded that the relay or one of its modules is of concern, contact GE Multilin or one of its representative for prompt
service.
1.4.4.2 IN-SERVICE 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. Visual inspection for any damage, corrosion, dust or loose wires.
4. Event recorder file download with further event analysis.
1.4.4.3 OUT-OF-SERVICE MAINTENANCE
Out-of-service maintenance:
1. Check wiring connections for firmness.
2. Analog values (current, voltages, analog inputs) injection test and metering accuracy verification. Calibrated test
equipment is required.
3. Protection elements setpoints 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.
To avoid deterioration of electrolytic capacitors, power up units that are stored
in a de-energized state once per year, for one hour continuously.
