Facilities need to perform installation tests, implement preventive maintenance programs, and perform comprehensive commissioning tests to verify the integrity of both existing protective relay systems and new protection systems. Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. For the purpose of this guideline, we define the protection system to include the entire protective relay system including all relay inputs and their sources, the protective relay or relays themselves, and the relay outputs all the way to the circuit breaker trip and close coils. Commissioning, on the other hand, is the final stage that confirms the entire integration of relays within the system's protection scheme before the system goes live.
In addition to customizing specific microprocessor-based relay capabilities, skilled integration engineers can also help utilities and industrial facilities design their microprocessor-based relay protection
Since type testing of a digital or numerical protection relay includes software and hardware testing, the type testing procedure is very complex and more challenging than a static or electromechanical relay.
