NERC PRC-005 is one of the most essential standards to ensure the safety and reliability of your bulk electric system. Originally adopted in February 2005, NERC PRC-005 continues to establish documentation programs and a maintenance schedule for all protection systems. This includes automatic reclosing and sudden pressure relaying which must function properly to maintain your system’s reliability
NERC PRC-005 includes a comprehensive list of tables which describe required minimum maintenance activities and their maximum maintenance intervals. PRC-005 Table 1-5 (Control Circuitry) and Table 5 (Sudden Pressure Devices) each require the actuation of your trip devices every six years and a total circuit check every 12 years. The infrequency of these tests can make them risky to perform. In addition, anything less than 100% accuracy of test performance can result in unanticipated consequences such as outages and system instability both inside and outside the plant.
In order to ensure compliance with NERC PRC-005 and protect your employees and assets, follow these best practices when performing your NERC activities:
Adopting these practices will help you prepare for successful testing, resulting in not only NERC PRC-005 compliance, but a safe and reliable system as well.
