Abstract
Computer simulation of partial discharge pulse propagation on one bay of GIS is performed by EMTP-ATP., which provides a reference for PD detection and location. The joint time-frequency analysis method is used for the pattern recognition of partial discharge, and the recognition results are better than other methods.
