【Abstract】 The principles of detection technique and it’s application to detect PD signals at ultra-high-frequency(UHF) are introduced. Computer simulation shows that the peak and phase characteristics of UHF PD signals can be got by acquisition card with 20 MHz sampling rate using detection technique, which can greatly reduce the demand of the acquisition system. The results show that the application of detection technique to detect UHF PD signals is feasible.更多还原
