Three-Phase Zinc Oxide Arrester Live Tester




Three-Phase Zinc Oxide Arrester Live Tester



 



It is a special instrument used to detect the electrical performance of zinc oxide arresters. This instrument is suitable for live or outage detection of zinc oxide arresters of various voltage levels, so as to timely discover dangerous defects such as internal insulation moisture and valve plate aging.



The instrument is simple to operate and easy to use. The whole measurement process is controlled by a single-chip microcomputer. It can measure the total current, resistive current and its harmonics, power frequency reference voltage and its harmonics, active power and phase difference of zinc oxide arresters. The large screen can display the real waveform of voltage and current. The instrument uses digital waveform analysis technology, adopts harmonic analysis and digital filtering and other software anti-interference methods to make the measurement results accurate and stable. It can accurately analyze the content of fundamental wave and 3rd to 7th harmonics, and can overcome the influence of inter-phase interference and correctly measure the resistive current of side-phase arresters. This machine is equipped with a high-speed panel printer and rechargeable battery, making it very convenient for testers to use on site. The instrument adopts a unique high-speed magnetic isolation digital sensor to directly collect input voltage and current signals, ensuring the reliability and safety of data.
