The Zinc Oxide Arrester Characteristic Tester is used for the measurement and analysis of leakage current of zinc oxide [MOA]. It is mainly used to measure the resistive current, thereby analyzing the degree of aging and moisture absorption of zinc oxide. On-site live testing complies with the requirements of the People's Republic of China electric power industry standard "DL474.5—92 Guidelines for Implementation of On-site Insulation Tests — Arrester Tests". This Zinc Oxide Arrester Characteristic Tester can also be used in the laboratory for factory and acceptance tests.
