The diffweence between Groud Fault Current and Short Circuit Current?
(OP)
What is the different between Ground Fault Current and Short Circuit Current?
I have heard someone arguing that Ground Fault Current is entirely different form Short Circuit current.
Is isn't a Ground Fault current eventually becomes Short Circuit current to trip the nearest circuit breaker,
I cannot find a clear cut definitions that separate the two to be entirely two different currents. Thank you in advance.

There can be other types of short circuit faults like phase to phase and bolted three-phase faults.

When studying networks and depending on the purpose of the study (protection coordination, arc flash, stability etc) you will consider different type of faults: 3 phase fault, phase to phase, p to ph to ground etc.
Most common SC type of fault will be phase to ground faults that will have a different value from say a 3 phase fault.

I think they are same eventually when it comes to short circuit currents....they may have differnt values...but they take different routs....

All are faults (a better term than short circuit I think).
Good on ya,

The enclosed diagram shows the most common type of faults and may help to visualize the worst scenario based on the system sequence impedances at the fault location.
