Product Overview:

MSBL-VX Zinc Oxide Surge Arrester Resistance Current Tester is a specialized instrument used to test the electrical performance of zinc oxide surge arresters. This instrument is suitable for live or power-off detection of various voltage levels of zinc oxide surge arresters, so as to timely detect dangerous defects such as insulation moisture and valve plate aging inside the equipment.

The instrument is easy to operate and use, and the entire measurement process is controlled by a human-machine interface. It can measure the full current, resistive current and its harmonics, power frequency reference voltage and its harmonics, active power and phase difference of zinc oxide lightning arrester. The large screen can display the real waveforms of voltage and current. The instrument uses digital waveform analysis technology and anti-interference methods such as harmonic analysis and digital filtering software to ensure accurate and stable measurement results. It can accurately analyze the content of fundamental waves and 3-9th harmonics, and overcome the influence of phase to phase interference to correctly measure the resistive current of edge phase lightning arresters.
