Hi,

I have to perform short circuit calculations, and I was looking at the parameter of "Breaker contact parting time" in the IEC 60909 Fault calculation window. what is the meaning of this value, I assume it is fault clearing time, let's say that for my system in the grid code I have clearing time of 200milisendos for short circuits, should I put there 0.2s?

Thank you
