摘要
氧化锌避雷器MOA是用来限制过电压的一种主要保护电器,由于其在运行中极易受潮,有必要对其进行在线监测。结合实际,介绍了几种常用的对MOA进行在线监测方法。
Metal-Oxide Arresters is a primary protecting equipment to limit the over-voltage. As it is extremely incline to be affected by the damp under running circumstance, it is necessary to carry on the on-line monitor on it. This paper introduces several online monitoring methods on MOA.
