摘要
阐述了金属氧化物避雷器(MOA)在线测试的方法及存在的问题,针对大多数运行的110 kV变电站中进线端只设有MOA而无电压互感器(TV)的情况,提出了2种简单、易行的MOA在线测试方法,并通过试验验证方法的可行性。
The on-line testing method of Metal Oxide Arrester （MOA） and its existing problems are expounded. Aiming at the status that most of 110 kV transformer substations equip with MOA but no TV, two simple and convenient MOA on-line testing methods are proposed, and the methods are proved feasible through experimental verification.
