Relay protection device testing cycle
Protective circuit functional testing, including lockout relay testing, must take place immediately upon installation, every 2 years thereafter, and upon any change in wiring. 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 standards. These required regular testing, adjustments and maintenance to ensure continued functioning. Relays contained bearings, springs, fixed and movable contacts, rotating. These devices safeguard assets and maintain power stability by swiftly detecting and isolating faults. This guide explores the different types of protection relays and their testing procedures, with a focus on tools like secondary injection test sets and three-phase relay test sets. Three developments are currently causing a significant increase in the amount of assets requiring testing and.
