HZ-20AS Handheld Zinc Oxide Lightning Arrester Tester
Overview
The HZ-20AS is designed to evaluate the electrical performance of zinc oxide arresters (MOA). It is suitable for on-site inspection of arresters at all voltage levels, as well as factory testing and acceptance testing in storage when power is disconnected.
By measuring parameters such as total current and resistive current, the tester can detect potential defects including internal insulation deterioration and valve element aging in zinc oxide arresters, helping to identify dangerous conditions before they lead to failure.
