摘要

Partial discharge may occur on overhead insulated lines of 10kV distribution network under polluted conditions. The uses of pulse current characteristics can provide a reference for equipment condition assessment. In order to master the transmission characteristics of partial discharge pulse current along the distribution overhead insulated line, this paper mainly builds a simulation model of single circuit overhead insulated line, and studies the influence of line height, wire cross-sectional area and phase spacing on the transmission characteristics of partial discharge pulse current.
