变电所中快速暂态电磁场强度由于开关操作暂态过程受多种因素影响.因此变电所中实际测t得到的场强数值分散性较大。不同电压等级变电所，用不同型式开关，实测得到的电场强度可达数十千伏/米(kV/m).磁场强度可达数百安培/米(A/m).美国对变电所中操作暂态电磁场的实测工作做的较多。作为一个例子，下表列出了美国电力研究院(EPRI)在115kV、250 kV、500 kV变电所中的实测结果。常规变电所内测点在母线下方地面，操作是断开一段短母线，一川纵潮洲娜朋洲川一0 0 0 0 0 00411:1l)即10 010加 ︵任守︸侧欲典匆 6 .0臼.《】火l()《a)T(5、留一。·““nlj 0 50几00 .，0.1 10 (任/A艺侧蔽2.()魂.硬)丫﹂)()口匕t卜卜片卜f乙仁0 t 0 0 0 0 005 .....-卜闭40加020化 (‘/V)侧旧要翻，::.:: l二‘.1.吐吐.吐2.《)4.(】6 .0划) 了卜卜┌────┬──────┐│ 一一J │八L，‘一’ ││习 ├──────┤│一一.1 │{犷V一· │└────┴──────┘0﹃-j门1 96，JD.任1 9 tl滩n乙oq乙 ︵三z淤巴侧翻要御 (一。一‘)洲.‘}12‘)一6(，义1‘，一‘， 喊d)T(5) 500 kV变电所内断开隔离开关时 的地面电场和磁场(a)GIS磁场;(b)GIS电场;(e)AIS滋场;(d)AIS电场b一and一onsuo kuolsu zonto一d一onelehong变电所快速暂态电磁场(fast transient elec-tromagnetie fields in substations)变电所中隔离开关切、合短母线时的暂态过程产生的电磁场。高压隔离开关操作时，触头间产生一系列电弧过程。
