TAO An-pei1, YANG Qing-he2, LIU Yong1, et al. Analysis on Reason for a GIS Earth Fault[J]. High voltageapparatus, 2012, 48(12): 139-142. DOI: 10.13296/j.1001-1609.hva.2012.12.028.
and it is more complex troubleshooting.GIS quickly and accurately determine the causes of failure to reduce outage time.This is the questions that engineering personnel are very concerned about.This article introduces a breakdown of gas-insulated metal-enclosed switchgear
which is due to installation process.Through the detailed experiment and field investigation
the failure causes are analyzed
at the same time some suggestions for the early detection of GIS defects and commissioning test are put forward.
