Studies of lightning overvoltages of 115 kV CMU GIS substation
This paper presents the analysis of lightning overvoltage for the new coming 115 kV CMU (ChiangMai University) GIS (Gas Insulated Switchgear) substation applying simplified models. The GIS being considered here is connected to an overhead line through XLPE underground cables. The sensitivity analysi...
