Understanding 2023 NFPA 70B
The 2023 version of NFPA 70B, now a standard, shifts from recommendations to mandatory language surrounding the implementation of electrical maintenance programs.
Installing and Maintaining Protective Relay Systems
NERC has developed Standard PRC-005, to ensure that all transmission and generation protection systems affecting the reliability of the BES are maintained and tested.
Protection System Maintenance Program following NERC PRC
Generation owners, transmission owners, and distribution providers are required to establish, implement, and maintain a documented maintenance program for their protection systems.
