This instrument uses high-frequency detection technology to measure partial discharge, and comprehensively uses computer technology, ultrasonic wave, transient ground wave sampling technology, analog electronic technology, high-speed signal acquisition technology and advanced digital signal processing technology. It is developed based on the Linux operating system platform and provides local Two-dimensional and three-dimensional maps of discharge, amplitude and phase spectrum waveforms and quantified values of discharge signals, detailed observation and analysis of single-cycle or multiple-cycle partial discharge pulse waveforms statically or dynamically, which can better evaluate partial discharge in electrical equipment Happening. It is suitable for daily inspection of the insulation performance of high-voltage cables, power transformers and other electrical equipment. It has the characteristics of high sensitivity and strong adaptability, and can effectively find their related insulation defects.
