An accurate arc model based on ATP-EMPT is built to analyze the impacts of cable＇s capacitive current on the arc intensity during 10kV non-loaded cable live breaking or connecting. According to the comprehensive and thorough simulation analysis, we can draw a conclusion that the greater the capacitive current is, the greater the arc intensity is. The research results of this paper provide guidance for the 10kV non-loaded cable live working and the selection of arc suppression strategy. It is of great theoretical significance and practical application value.
