For a given power system, a single line to ground fault occurred at phase
A
at a certain bus in the system. This fault led to different currents in the phases and unbalanced conditions. Figure (2) shows the connected sequence diagram that represents the fault condition. i. Calculate the sequence currents
I_(0),I_(1)
and
I_(2)
. ii. Calculate the three phases fault current
I_(A),I_(B)
and
Ic
. iii. If the faulted bus was the motor bus in question 3, calculate the actual fault current.
