Analysis of generator outage caused by HV plant transformer LV side non segregated busbar failure

Abstract

Abstract:

Abstract:The author studied on a generator outage,which caused by plant transformer LV side non segregated enclosed busbar failure.Based on the treatment of this accident and record analysis,the author indicated that the direct reason of this accident is the enclosure of LV side non segregated busbar was not well sealed,and insulator was damped.This paper also included the preventive measurement based on aspects of operation and equipment maintenance.

Key words: Keywords:non segregated enclosed busbar, single phase ground failure, damp, room temperature vulcanized silicone rubber, busbar heat tracing
