Abstract

This paper presents a decomposition and reconstruction algorithm based on wavelet packet theory.Disturbance partial discharge signal in HV transformer was designed for computer simulating.The extraction of the partial discharge signal in HV transformer is studied.Computer simulation results show the partial discharge can be extracted from strong carried disturbance and RF disturbance by the algorithm.
