- In this paper, the explosion accident of a 220kV current transformer in a 220kV substation is studied. It uses method of scene investigation and test to analyses the accident based on the principle and characteristics of current transformer. Through the analysis, this paper holds that reducing in main insulation electrical strength caused by Long-term high harmonic voltage and main insulation breakdown caused by flicker impact are main causes of the accident. And it also proposes a variety of management methods and technical measures to avoid this kind of accident. This paper provides a reference for the analysis of the same type of accident.
