研究了气体绝缘开关设备（GIS）中金属颗粒对介质涂层电极的影响。在微观表面降解的背景下，观察到各种意想不到的现象。一个简化的测试设置被用来执行基本的调查。低频行为进行了检查，在直流和50赫兹交流电压在加压SF6气体。
Dielectric coated electrodes in gas insulated switchgear (GIS) components were studied in presence of metallic particles. In the context of microscopic surface degradations, various unexpected phenomena were observed. A simplified test set-up was used to perform fundamental investigations. Low frequency behaviour was examined at DC and 50 Hz AC voltage in pressurized SF6 gas.
