HYG-IV Zinc Oxide Arrester Live Tester is a special instrument for testing the electrical performance of Zinc Oxide Arrester. It is suitable for live or outage detection of Zinc Oxide Arrester of various voltage levels, so as to find out the dangerous defects such as damp insulation and aging of valve plates in time.

The instrument is simple to operate and easy to use. The whole measuring process is controlled by a computer. 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 arrester. The real waveform of voltage and current can be displayed on a large screen. The instrument uses digital waveform analysis technology and software anti-interference methods such as harmonic analysis and digital filtering to make the measurement results accurate and stable. It can accurately analyze the content of fundamental and third to seventh harmonics, overcome the influence of inter-phase interference, and correctly measure the resistive current of side-phase arrester.
