The North American Electric Reliability Corporation (NERC) is the regulatory authority responsible for the reliability of the Bulk Electric System (BES) in North America. The new NERC Standard PRC-005 was developed to improve BES reliability by regulating routine maintenance and testing activities of protection system components used in generation, transmission, and distribution entities. The objective of this report is to provide a comprehensive Best Practices report to the CEATI SEAM Interest Group for implementing the new NERC PRC-005 standard in establishing a proper PSMP program and providing a set of evolving strategies for their consideration. This report provides CEATI member utilities with a comprehensive understanding of the NERC PRC-005 requirements, as well as a comparison between PRC-005 and similar requirements from regulatory authorities in other jurisdictions. Furthermore, maintenance requirements and techniques to determine the condition of dc batteries were identified in addition to available monitoring techniques for all protection component groups, except protective relays and communication systems. A review of current industry practices was conducted regarding their maintenance activities and documentation methods. Based on this information, roadmaps and/or strategies for implementing maintenance programs to achieve compliance with the standard were outlined. Recommendations were also made to NERC that would help improve the standard by including other maintenance methods and/or cost-effective approaches.
