Product Introduction

The rechargeable zinc oxide arrester tester is specially used to detect internal defects such as poor contact between valve elements of gapless zinc oxide arresters (MOA) at 10kV and below. It is essential for power plants and substations to perform DC 1mA voltage (U1mA) and leakage current test at 0.75 U1mA on metal oxide arresters before and during the annual thunderstorm season when necessary. 

Our company has improved the instrument based on field measurement requirements, integrating the DC high-voltage power supply, measurement, and control system, reducing the instrument's size and weight. It is an indispensable device for on-site inspection in power systems and zinc oxide arrester manufacturing plants.
