Product Introduction
The rechargeable zinc oxide arrester tester is specially used to detect internal defects caused by poor contact between valve elements of gapless zinc oxide arresters (MOA) at 10kV and below. It is necessary for power plants and substations to perform DC 1mA voltage (U1mA) and leakage current tests at 0.75 U1mA on metal oxide arresters before the annual thunderstorm season and when needed.
Our company has improved the instrument based on field measurement needs, organically combining the DC high-voltage power supply, measurement, and control system, reducing the instrument's size and weight. It is an essential device for on-site inspection in the power system and for zinc oxide arrester manufacturers.
