Brief Analysis of High Voltage Test Technology

and Method of Metal Oxide Surge Arrester

Hou Xin-li

[Abstract]The use of metal oxide arresters is affected by environmental pollution and humidity. After being damp， the resistance is easy to age， resulting in abnormal temperature rise and even explosion. Therefore， preventive tests should be carried out on metal oxide arresters on a regular basis. This article discusses the high-voltage test techniques and methods of metal oxide arresters.
