Ungrounded system, service restoration, fault isolation
Fault isolation and service restoration are very important functions of Distribution Automation System (DAS). A conventional method to determine a fault section in ungrounded systems requires many successive outage invocations. In this paper an efficient fault section isolation method and service restoration method to spend much less time than the conventional one are proposed. The proposed method utilizes the information exchange between feeders connected.
