Inspection of relay protection maintenance control board
What is the Checklist for HV & EHV Protection Control and Relay Panel
The purpose of a pre dispatch inspection is to verify that control and relay panels meet all technical, safety, and quality requirements before they leave the factory.
TD-3323S
This test determines whether protective relays, fault pressure relays, reclosing relays, reclosing supervisory relays, and associated control schemes are operating properly.
Testing and Maintenance of Protective Relays
The performance of protective relay is affected by maintenance. Basic requirements of sensitivity, selectivity, reliability and stability can be satisfied only if the maintenance is excellent.
