TIME-FREQUENCY ANALYSIS OF SIGNALS RADIATED FROM CORONA DISCHARGE OF ISOLATED CONDUCTOR

摘要：

According to the principle of energy storage of capacitor,a simulation system of corona discharge of isolated conductor was given in this paper.The characteristics of the signals radiated from corona discharge were analyzed both in time-domain and frequency-domain.The results indicate that the signals have a damped oscillation waveform under different discharge voltage，and their amplitude increase with the rising of the discharge voltage；the directions of the first pulse of the radiation signals are opposite under different polarities of the discharge voltage；the signals amplitude varies obviously under difrerent values of the charging voltage and the conduction path of the discharge current affects the signalfrequency range obviously.
