摘要：
Sulphur hexafluoride (SF6) gas-insulated substations (GIS) are exposed to the same types of overvoltages as conventional substations, such as lightning overvoltages, switching overvoltages and temporary overvoltages. Possible means to limit overvoltages in a GIS are active gap (SIG) surge arresters and metal oxide (ZnO) surge arresters. The objective of this work is to study the effects of the system configuration on the performance of these two types of overvoltage limiting devices. The results obtained from the study are presented and discussed, and some general conclusions are suggested. Copyright (C) 1996 Elsevier Science Ltd
