Testing Panel

The electrical panel testing also involves checking all the wiring and incoming/outgoing signals to the relays for the proper operation of the protection logic.

The suitable panel testing is carried out to make sure continuity of operation. The panel testing in the factory, commissioning or during maintenance programs goes through many quality analysis and test procedures with reference to the electrical operation, which usually covers dielectric resistance, relay testing, functional testing of the protective scheme, breakers testing, wiring and polarity continuity, and other operational checks.

The electrical panel testing also involves checking all the wiring and incoming/outgoing signals to the relays for the proper operation of the protection logic. The cohesion of the protection circuit during the panel testing is a key factor in the security.

Point-to-point checks of wiring diagram are usual in the panel testing, and any of the mentioned secondary injection units are used as current/voltage sources to perform verification of the different control and signalling circuits, through the generation of nominal and fault values, and simulate and check the execution of protection sequences.
