Relay testings
Relay performance tests address two questions. Is the relay operating as it was designed? Is the relay being applied properly? Integrity tests are intended to answer the first, and application tests the second. In the past, users have concentrated on integrity tests using relatively simple equipment in the field. Application tests required bulky and expensive equipment which was usually only available in relay manufacturers' plants, or in research laboratories. Historically, field test equipment was only suitable for steady-state tests and limited dynamic state simulations. Manufacturers and users developed comprehensive test plans to ensure the integrity of relays using passive test equipment. Integrity tests were also designed to be performed in the field using simple equipment. With common applications, the manufacturers application tests done during relay development will usually suffice to ensure correct operation under normal circumstances.
