Analysis and Treatment of Multi-point Grounding Faults in the Core of a 10 kV Distribution Transformer
Transformer core grounding fault is harmful,very easy to cause insulation burning accident.This paper takes a 10 kV transformer core multi-point grounding fault as an example,through the dismantling inspection and measurement of insulation resistance,analyses the transformer core multi-point grounding fault formation reasons,combined with the actual operation of the transformer,gives the operation and maintenance of preventive measures.
