Zinc oxide arrester tester effectively detects internal insulation dampness of arresters
Zinc oxide arrester tester is a specialized instrument used in power systems to test the electrical performance of metal oxide arresters (MOA). By measuring key parameters such as leakage current and resistive current of the arrester, it determines whether there are hidden dangers such as internal insulation dampness, valve plate aging, or deterioration. It is an important testing tool for ensuring the lightning protection safety of power systems.
Depending on whether the arrester is in operation during testing, the instrument is mainly divided into two modes: live testing and outage testing.
