I. Product Purpose
YTC620HZinc Oxide Arrester Live Tester is a specialized instrument used to detect the electrical performance ofzinc oxide arrester testers. It is suitable for live or outage testing of zinc oxide arresters of various voltage levels, thereby promptly detecting dangerous defects such as internal insulation moisture and valve plate aging.
The instrument is simple to operate and easy to use. The entire measurement process is controlled by an industrial computer. 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, employing software anti-interference methods such as harmonic analysis and digital filtering to ensure accurate and stable measurement results. 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.
