Application of Zinc Oxide Surge Arrester Online Monitoring System

Product Usage

It is an 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, 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 an industrial computer. 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 utilizes digital waveform analysis technology and employs software anti-interference methods such as harmonic analysis and digital filtering to ensure accurate and stable measurement results. It can accurately analyze the fundamental wave and3～7The content of subharmonics can overcome the interference between phases and accurately measure the resistive current of edge phase lightning arresters.
