1、 Product Overview:

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

The zinc oxide lightning arrester characteristic tester is easy to operate and use. The entire measurement process is controlled by the human-machine interface and 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 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, which can accurately analyze the content of fundamental waves and 3-9th harmonics.
