Research of Testing and Calibration System about Ultrasonic and UHF Partial Discharge Detection Device

摘要

The testing and calibration of high voltage electrical equipment partial discharge detection device play a crucial role to the safe and reliable operation in power system. In this paper, the overall structure design of ultrasonic and UHF partial discharge detection devices is build, and the power amplifier module, high-speed data acquisition module and filter module are designed, and wavelet transform method is adopted to improve the interference of noise. The test system put forward in this paper is instructive to the research of ultrasonic and UHF partial discharge detection device.
