Design of HV Pulse Generator Applied in PEA Space Charge Measurement System
The pulsed electro-acoustic (PEA) method is a popular technology of measuring the space charge distribution.The premise of using this method is to create a high voltage pulse.This paper expounds the principle of PEA measurement of space charge in the dielectric,and analyzes the influence of high voltage pulse waveform on the measuring signal.On the basis of analyzing the traditional high voltage pulse generator,a new-type HV pulse generator with phase detection is introduced,so that the PEA space charge measurement system can fit the cable insulation test under AC voltage.This generator can form 5 kV steep pulse voltage signal of 50 ns,100 ns and 200 ns.
