Abstract
This paper describes the design and application of a three-phase device used to isolate a faulted spur from the main feeder. This allows restoration of service to the feeder. Visibly open contacts and provisions for grounding the faulted spur provides the operating conditions for repairing the fault. When the fault is repaired the device can be triggered to close spring-loaded contacts and reconnect the spur to the feeder without interruption of the feeder. The device is designed to operate on a 27 kV, 600 A system with a fault-close rating of 40 kA for 10 cycles
