LONG DESCRIPTION: ERCOT has received a proposal from Oncor Electric Delivery Company LLC (Oncor) to add a Remedial Action Scheme (RAS) at Culberson Loop. The Culberson Loop RAS consists of redundant relays placed at every transmission switching station, wired to monitor the status of each transmission line terminal on the Culberson Loop. Under specific system configurations voltage instability can occur. Oncor’s proposed RAS will automatically perform remedial tripping in response to the specific contingencies of concern.
