  • Product Introduction

The ZC-710B zinc oxide lightning arrester tester is a specialized instrument used to test the electrical performance of zinc oxide lightning arresters. This instrument is suitable for live or power outage detection of zinc oxide lightning arresters of various voltage levels, so as to timely detect dangerous defects such as insulation moisture and valve aging inside the equipment.

The instrument is easy to operate and easy to use, and the entire measurement process is controlled by the 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 the zinc oxide arrester. The large screen can display the true waveform of voltage and current. The instrument utilizes digital waveform analysis technology and 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 fundamental and 3rd to 9th harmonics, overcome the influence of phase interference, and accurately measure the resistive current of the side phase lightning arrester.
