We had a bad regulator on a primary line. Voltage is 7.2, the fault indicators did not work. The indicators are Linam 100 amp trip, made by Chance. The lineman put the indicators on both sides of the regulator, showed white. Disconnected regulator, tried the OCR, and it closed right in and held. Thank you, Bob

What was the original symptom of the bad regulator?

Question was, why did the indicators not work. When they disconnected the regulator the OCR stayed in. That makes it a bad regulator. I did find out why they did not work.I will answer nice storys questions, no ,yes, we did not know the fault current at the time of the outage. After getting with our engineer, the fault current was 130 amps at the ocr. A couple miles away the fault current was less than 100 amps. Thank you for your help. Bob
