engineering recuitment HAL Management & Design Trainee Mock Test 2023 Power Systems Fault Analysis Line To Ground Fault
The severity of line to ground and three phase faults is to be same. If the terminal voltage is 1.0 pu, Z1 = Z2 = j 0.1 pu and Z0 = j 0.05 pu for an alternator, then the required inductive reactance for neutral grounding is
1
0.0166 pu
2
0.05 pu
3
0.1 pu
4
0.15 pu
