Power Relay Protection Maintenance Procedures
Relay maintenance generally consists of : Inspection and burnishing of contacts. Adjustments checking (iv) Breakers tripped by manual contact closing. From initial assessment and planning to data collection, analysis, and procedure refinement, each step is critical to achieving a sustainable and efficient maintenance program. In this section, we. Acceptance tests fall into two categories : (i) On new relays which are to be used for the first time. (ii) On relay types which have been used earlier, only minimum necessary checks should. This paper is an overview of recommended maintenance practices but does not include tests for specific types or brands of protection equipment. This guide is intended to bring the Western Electricity Coordinating Council (WECC) into compliance with the North American Electric Reliability Council (NERC) Planning. Protective circuit functional testing, including lockout relay testing, must take place immediately upon installation, every 2 years thereafter, and upon any change in wiring.
