YBL-IV Zinc Oxide Arrester Tester
DARUI Electric recommends
The rechargeable zinc oxide arrester tester is specially used to detect internal defects caused by poor contact between the valve plates of gapless zinc oxide arresters (MOA) at 10kV and above. It is essential 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 necessary.
Our company has improved the instrument based on actual field measurement requirements, integrating the DC high-voltage power supply, measurement, and control systems to reduce the instrument's size and weight. It is an indispensable device for on-site inspection in the power system and zinc oxide arrester manufacturing plants.
