Switchgear Maintenance Procedures

Relay Protection Cabinet Maintenance Procedures

Relay maintenance generally consists of : Inspection and burnishing of contacts. Adjustments checking (iv) Breakers tripped by manual contact closing. Rare operation, critical function: Protective relays may operate only once every several. Section 11. 4 of the WECC Minimum Operating Reliability Criteria stipulates that “Each system shall provide for periodic testing of protective relay systems and remedial action schemes which impact the reliability and security of the interconnected system operation. Establish and maintain its performance-based maintenance (PBM) intervals, when used, in accordance with the Tables of PRC-005. If applicable, documentation is required detailing how verified protection segments overlap to ensure there is not a gap. This utility standard establishes the requirements for testing and maintaining protection systems, automatic reclosing, and sudden pressure relaying.
