1. using Voltage of 14,400V calcukate fault current for phase to phase fault at point A on the picture

2. using voltage of 13,800V calcculate the fault current for 3 phase fault at point B on the pictture

3.If the current at the point of the fault is 1680A what is the current suppies to the feeder relay?

4.If the current at the point of the fault is 1518AC what is the current supplies for to the feeder relay

point B is to the right of j4.3ohms

51 Feeder 50 51 Recloser 50 600/5A 2.0 ohms 23.5 ohms 500/5A 2.5 ohms 14.3 ohms ur Wrigem Xsystem = J0.80 ohms
