In a power network, 375 kV is recorded at a 400 kV bus. A 45 MVAR, 400 kV shunt reactor is connected to the bus. What is the reactive power absorbed by the shunt reactor?

• A. 49.55 MVAR
• B. 59.55 MVAR
• C. 39.55 MVAR
• D. 69.55 MVAR

Answer: (C)

Q = V²/X
X = 400²/45
= 3555.55 ohm
For 375 kV,
Q = 375²/3555.55
= 39.55 kVAR
