I have a Question. It is about resonant condition(s).
Is it possible to do quick calculation to see if resonance is the problem, or do I have to run EMTP?
My case: New feeder, 138 kV to 27 kV, energized (from 138kV) for the first time - tripped upon being energized. The cause of the trip was a...

A little bit more info about my problem:
Using Aspen One liner I fault the bus itself, and not the adjacent feeders. I get 41 kA which is 1 kA more then my lowest breaker rating (40 kA).
I thought that all breakers would be subject to the same duty. However I was told that they...
I need Help.
Using ASPEN One Liner I found the 3-phase, 2-phase and 1-phase short circuit values for each bus in my system.
However, my real system is build on ring buses.
The question is how can I calculate each breaker (in the ring bus) fault duty. I think this is called IBA (individual...
