245kV sf6 Switchgear explain
2011/5/9As you have stated, your nominal voltage is 220kV and you chose 245kV switchgear and I saw it. What I I don't understand here is how you will obtain the fault current by selecting the higher voltage of switchgear since the switchgear suppliers suggests that they designs switchgear with two level of voltage just to meet the transient voltage.
