Fault Cause Analysis of Elbow Cable Joint of 10kV Pole-Type Transformer caused by Grounding Non-standard

Abstract

This paper introduces the basic structure of elbow cable joint of 10kV pole-type transformer. By actual measurement and laboratory simulation, author emphatically analyzes the incorrect grounding of pole-type transformer, which is an important reason for the fault causes. At last, the solutions and preventive measures are put forward.
