Zinc oxide lightning arrester DC leakage tester

Brief introduction

This instrument is designed according to the relevant testing standards for "AC gapless zinc oxide lightning arresters" and is specifically designed for testing low current residual voltage/leakage current of lightning arresters and zinc oxide resistors at rated voltages of 10kV and below.Zinc oxide lightning arrester DC leakage testerFor lightning arrester and zinc oxide resistor manufacturers, performance testing of lightning arrester and zinc oxide resistor in power systems is an essential testing method. It integrates DC high-voltage power supply, measurement, and control system, and can complete the measurement of U1mA and 0.75U1mA leakage current at once. It is small in size, light in weight, practical, and easy to operate.

Product Features
1. Fully automatic measurement, easy and fast operation
The precise closed-loop adjustment of 1mA current and 0.75 times DC reference voltage is carried out using the principle of automatic control. The measurement process is controlled by a microcomputer, and only one button is needed to automatically measure the DC reference voltage at 1mA and the leakage current at 0.75 times DC reference voltage of the zinc oxide arrester. The entire process only takes 15 seconds, making it very suitable for batch measurement.
