Why is LL bigger than 3ph fault
Why is LL bigger than 3ph fault
(OP)
Hi,
I have just obtained some fault currents result from using SKM, it shows that both the SLG and LL(phase to phase) is much higher than the 3ph fault.
With SLG fault I can figure out that it is possible (due to low sequence impedance) but why is the phase to phase fault bigger than the 3ph fault?
Thanks

RE: Why is LL bigger than 3ph fault
it should be LLG (double phase to ground fault) not LL....
Why is LLG bigger than 3ph fault? Because of low zero sequence impedance from generators and transformers?
Thanks
