If you are a Generation Owner, Transmission Owner, Distribution Provider or you provide service and maintenance to any of the aforementioned entities you are most likely struggling with maintenance compliance for your protection system. Or more specific, as the North American Electric Reliability Corporation (NERC) defines the Protection System –
• Protective relays which respond to electrical quantities,
• Communications systems necessary for correct operation of protective functions,
• Voltage and current sensing devices providing inputs to protective relays,
• Station dc supply associated with protective functions (including station batteries, battery chargers, and non-battery-based dc supply), and
• Control circuitry associated with protective functions through the trip coil(s) of the circuit breakers or other interrupting devices.
Since the beginning of the mandatory and enforceable standards on June 18, 2007, Protection and Control Standard PRC-005 has been reported to be the most frequently violated standard. Reported violations fall into two basic requirement levels – Maintenance and Testing program and Documentation Provided on Request.
Let’s face it, keeping up these enforceable standards presents challenges. Protec Equipment Resources understands the challenges that our clients are facing and currently stocks a vast inventory of test and measurement equipment and software compliant with the maintenance activities outlined in most current PRC-005-2, Draft 3.
