Concept:
The surge impedance or characteristic impedance of a long transmission line is given by,
Z is series impedance per unit length per phase
Y is shunt admittance per unit length per phase
- The surge Impedance for the transmission line is about 400 ohms it is around 40 ohms for underground cables.
Surge impedance loading (SIL):
- Surge impedance loading is defined as the power load in which the total reactive power of the lines becomes zero.
- The reactive power generated by the shunt capacitance is consumed by the series inductance of the line.
Calculation:
Given:
Surge impedance (ZC) = 400 Ω
Voltage (V) = 200 kV

Calculation of SIL (Surge Impedance Loading)
To calculate the Surge Impedance Loading (SIL) of a transmission line, we can use the formula:
\[ SIL = \frac{V^2}{Z} \]
Given data:
- Line voltage (V) = 200 kV = 200,000 V
- Surge impedance (Z) = 400 ohm
Calculation:
\[ SIL = \frac{(200,000)^2}{400} = 100,000,000 / 400 = 250,000 \text{ VA} \]
\[ SIL = 250,000 \text{ VA} = 250 \text{ kVA} = 250 \text{ MW} \]
Therefore, the Surge Impedance Loading (SIL) of the transmission line for the given configuration is 250 MW, which is closest to option B - 100 MW.
