Overview

YHD-20 Wireless Zinc Oxide Surge Arrester Tester is an 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.

Product Details

1、 Overview:

The resistive current tester for zinc oxide lightning arresters is a specialized instrument used for on-site and laboratory testing of various electrical parameters related to lightning arresters. It is widely used in on-site online monitoring (live testing) and laboratory testing (power-off maintenance) of zinc oxide lightning arresters. Comply with the requirements of the power industry standard of the People's Republic of China, "DL474.5-92 Implementation Guidelines for On site Insulation Test - Surge Arrester Test". This instrument adopts advanced technologies such as microcomputer sampling and control, and can measure the full current, third harmonic, resistive current, peak resistive current, capacitive current, active power, etc. of zinc oxide lightning arrester under power frequency voltage. And display the waveform of voltage and current and print out the test data. Adopting a large screen LCD display and Chinese character menu prompts for operation, it enhances the human-machine exchange function and provides on-site waveform display. This instrument has the characteristics of simple wiring, high measurement accuracy, and strong reliability. The instrument is small in size, lightweight, and adopts an integrated design, making it easy to carry and perform field operations.
