The objective of a uniform Relay Test and Maintenance program is to insure the integrity of the protection system on a periodic basis after installation. Calibration testing is required to verify relay
Protection Relay Testing and Commissioning
The testing and verification of relay protection devices can be divided into four groups: Type tests are needed to prove that a protection relay meets the claimed specification and follows all relevant
PROTECTIVE RELAY TESTING
Acceptance testing, commissioning, and startup will include control power tests, current transformer and potential transformer tests, and any other device testing associated with the protective relay.
Installing and Maintaining Protective Relay Systems
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
FIST 3-8-March18-2010
Although testing of individual components may take place on a regular basis (e.g., relay calibration and lockout relay testing), it is essential to test the entire protection circuit, including wiring, and all
