Use this PRC-005 relay maintenance and testing record to document inspection, functional testing, calibration, and as-left settings for protective relays. Transform your raw data into insightful reports with just one click using DataCalculus. In the dynamic realm of electric power transmission, control, and distribution, Relay Protection Engineers play a pivotal role in safeguarding power systems. Facility /. A comprehensive relay protection system maintenance checklist ensures that every relay, control circuit, and protection scheme receives the verification it needs to perform reliably under fault conditions. Implement and follow the PSMP for PBM as per PRC-005. Establish and maintain its. Relay settings records are critical for protection coordination studies and maintenance audits. This Excel template provides a structured relay schedule with columns: Relay Tag, Make & Model, Location, Protected Equipment, Rated Current, CT Ratio, Pickup (Is), TMS, Curve Type (SI/VI/EI/DT), Highset. Protective circuit functional testing, including lockout relay testing, must take place immediately upon installation, every 2 years thereafter, and upon any change in wiring.
