Differentiation and solution of 6kV system grounding on one line and PT fuse failure

Abstract

Abstract:

Abstract:Modern large scale power plants with 6kV are mostly using neutral point ungrounded system.Some of operators are easy to make misjudgment of one line grounding and PT fuse failure.Based on the electrical principle and case study,this paper brought up two types of trouble shooting methods and the difference between this two types,which helps operators judging and handling obstacles are put forward.
