WDYZ-201 Zinc oxide arrester live tester is a special instrument for testing the electrical performance of zinc oxide arresters. This instrument is suitable for live or power failure detection of zinc oxide arresters of various voltage levels. Dangerous defects such as aging.
The instrument is simple to operate and easy to use. The whole measurement process is controlled by the man-machine interface. It can measure the full current, resistive current and its harmonics, power frequency reference voltage and its harmonics, active power and phase difference of zinc oxide arresters. Large screen Real waveforms of voltage and current can be displayed. The instrument uses digital waveform analysis technology, adopts software anti-interference methods such as harmonic analysis and digital filtering to make the measurement results accurate and stable, and can accurately analyze the content of the fundamental wave and the 3rd to 9th harmonics.
