Fault current calculation
If1_1 = -j3.92157
Fault current=If1=3If1_1=-j11.8
Short circuit current on the transmission line in all the three phases
If_a_12=
2.745098i
If_b_12=
- 2.0377068 + 0.3921569i
If_b_12=
- 2.0377068 + 0.3921569i
short circuit current phase(a) of the generator
Ifa_G = -j4.75465
Voltage of the healthy phases of the bus 1
Vf_b_1=-0.2647 - j0.86603
Vf_c_1=-0.2647 + j0.86603
