The live tester for zinc oxide arrester of Wuhan Huayi Guodian Power Equipment Co., Ltd. is a special instrument for testing the electrical performance of zinc oxide arrester. The instrument is suitable for detecting the live or power failure of zinc oxide arrester with various voltage levels, so as to find out the dangerous defects such as damp insulation inside the equipment and aging valve plate in time. The instrument is simple to operate and convenient to use. The whole measurement process is controlled by a microcomputer. 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 waveforms of voltage and current can be displayed on the big screen. The instrument adopts 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 contents of fundamental wave and 3rd ~ 7th harmonics, overcome the influence of interphase interference, and correctly measure the resistive current of side-phase arrester.
