Visual and Mechanical Inspection Testing and maintenance of protective relays always begin with a comprehensive visual and mechanical inspection. Protective relays are extensively utilized throughout the power system to promptly remove any element from service experiencing a short circuit, operating abnormally, or posing a risk to system operation. Instrument transformers support the relaying equipment in this task by sensing. This happens because the main function of protection devices is related to operation under fault conditions so these devices cannot be tested under normal operating conditions. (ii) On relay types which. THEY SHOULD BE GIVEN FIRST LINE MAINTENANCE ATTENTION. ” relay may only need to operate for 0. When a fault is detected, the relay sends a signal to circuit breakers to isolate the faulty section, preventing damage to equipment and minimizing.
