Determine the value of inductance of arc suppressor coil to be connected between the neutral and ground to neutralize the charging current of overhead line having the line to ground capacitance equal to 0.2 μF. If the supply frequency is 50 Hz and the operating voltage is 132 kV, find the kVA rating of the coil.

Determine the value of inductance of arc suppressor coil to be connect

1.	Determine the value of inductance of arc suppressor coil to be connected between the neutral and ground to neutralize the charging current of overhead line having the line to ground capacitance equal to 0.2 μF. If the supply frequency is 50 Hz and the operating voltage is 132 kV, find the kVA rating of the coil.
A.	16.89 H, 1.095 × 103 kVA
B.	20.89 H, 1.095 × 103 kVA
C.	16.89 mH, 3.095 × 103 kVA
D.	16.89 μH, 1.095 × 103 kVA
Answer» B. 20.89 H, 1.095 × 103 kVA
