Relay Protection Inspection and Operation Maintenance
Relay maintenance generally consists of : Inspection and burnishing of contacts. Adjustments checking (iv) Breakers tripped by manual contact closing. Relay protection systems are among the most critical—and most overlooked—components in electrical infrastructure. These devices spend years in standby mode, waiting to isolate faults in milliseconds when called upon. Yet without structured, documented maintenance, organizations often discover relay. Acceptance tests are performed in presence of the customer or by the customer. Most frequently they are performed by simulating test. Protective circuit functional testing, including lockout relay testing, must take place immediately upon installation, every 2 years thereafter, and upon any change in wiring.
