The wireless zinc oxide arrester tester is a special instrument used to detect the electrical performance of zinc oxide arresters. It is suitable for live-line or outage testing of zinc oxide arresters of various voltage levels, thereby timely discovering dangerous defects such as internal insulation moisture and valve plate aging. The instrument is simple to operate and convenient to use. The entire measurement process is controlled by a microcontroller. 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 waveforms of voltage and current. The instrument uses digital waveform analysis technology, adopts software anti-interference methods such as harmonic analysis and digital filtering to make measurement results accurate and stable. It can accurately analyze the content of the fundamental wave and 3rd to 7th harmonics, and can overcome the influence of inter-phase interference to 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 field personnel to use. The instrument uses a unique high-speed magnetic isolation digital sensor to directly collect input voltage and current signals, ensuring data reliability and safety.
