The zinc oxide lightning arrester live testing instrument is used to test the electrical performance of each phase of zinc oxide lightning arrester (MOA). This instrument is suitable for on-site live detection of zinc oxide lightning arresters of various voltage levels, as well as factory and acceptance tests conducted in the laboratory under power outage conditions. By measuring parameters such as full current and resistive current, dangerous defects such as dampness in the internal insulation of zinc oxide lightning arresters and aging of valve plates can be detected in a timely manner.
