I would like to calculate the single phase-ground fault current, but have limited information from the utility. For example, we have information like the 3 phase fault from the transmission pole as well as from each terminal near the faulted transmission pole. From this can we calculate the single phase to ground fault current? If so how?
Line Voltage: 115kV
At the faulted transmission pole:
3IO Mag At Fault (Amps)
3I0 Ang At Fault (Degrees) -53.4
From Terminal 1: 3IO Mag At Terminal 1(Amps) 2926 3I0 Ang At Terminal 1(Degrees) -53.9
From Terminal 2: 3IO Mag At Terminal 2 (Amps) 112 3I0 Ang At Terminal 2 (Degrees) -49.8
