Single Phase Zinc Oxide Lightning Arrester Tester
This Tester is used to verify the electrical performance of Zinc Oxide Arrester. The instrument is suitable for various kinds of voltage levels zinc oxide arrester de-energized testing or energized testing, thus define the risk and inner insulation moisture and valve aging defects.
The instrument is easy to operate and convenient to use. The whole process of measurement is controlled by a single chip microcomputer. It can measure the full current, resistive current and its harmonic, power frequency reference voltage and the harmonic, active power and phase difference of the Zinc Oxide lightning arrester. The real waveform of voltage and current can be displayed on the large screen. The instrument adopts digital waveform analysis technology, software anti-interference methods such as harmonic analysis and digital filtering to make the measurement result accurate and stable, can accurately analyze the content of the fundamental and 3~7th harmonic, and can overcome the influence of interphase interference, and measure the resistive current of the side phase arrester correctly.
