Zinc oxide arrester parameter characteristic tester

Zinc oxide lightning arrester electrification tester is a special instrument used to test the electrical performance of zinc oxide lightning arrester, the instrument is suitable for various voltage levels of zinc oxide lightning arrester electrification or power failure detection, so as to timely find the equipment internal insulation moisture and valve plate aging and other dangerous defects.

The instrument is simple to operate and easy to use, and the measurement process is controlled by the microcomputer. It can measure the current, resistance current and its harmonics, power frequency reference voltage and its harmonics, active power and phase difference of the zinc oxide arrester. The large screen can display the real waveform of voltage and current.

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, and can accurately analyze the content of fundamental wave and 3 〜 7 harmonics, and can overcome the influence of interphase interference, and correctly measure the resistance current of edge phase arrester.
