Applicability
PRC-005-1 - Transmission and Generation Protection System Maintenance and TestingUse SHIFT+ENTER to open the menu (new window).
Transmission Owner; Generator Owner; Distribution Provider

 Purpose of the drafting/revisions

The request asks for clarification on the following:
  • Does R1 require a maintenance and testing program for the battery chargers for the “station batteries” that are considered part of the Protection System?
  • Does R1 require a maintenance and testing program for auxiliary relays and sensing devices? If so, what types of auxiliary relays and sensing devices? (i.e. transformer sudden pressure relays)
  • Does R1 require maintenance and testing of transmission line re-closing relays?
  • Does R1 require a maintenance and testing program for the DC circuitry that is just the circuitry with relays and devices that control actions on breakers, etc., or does R1 require a program for the entire circuit from the battery charger to the relays to circuit breakers and all associated wiring?
  • For R1, what are examples of "associated communications systems" that are part of “Protection Systems” that require a maintenance and testing program?
