    ΜF. The length of the line is 50 km and the surge impedance is 400 Ω. Determine the surge impedance loading (SIL) and the surge impedance voltage (SIV) at the circuit breaker terminal.

    SIL = surge impedance loading
    SIV = surge impedance voltage

    We can use the following formulas to calculate SIL and SIV:

    SIL = (Vp / √2)^2 / Z0
    SIV = Vp / √2

    where Vp is the peak voltage of the surge and Z0 is the surge impedance of the line.

    To find Vp, we can use the formula:

    Vp = √2 x Vrms

    where Vrms is the rated voltage of the system, which is 132 kV.

    Vp = √2 x 132 kV = 186.4 kV

    Now we can calculate the surge impedance:

    Z0 = √(L/C) = √(50 mH / 0.05 μF) = 200 Ω

    Using these values, we can calculate SIL:

    SIL = (186.4 kV / √2)^2 / 200 Ω = 8.3 MW

    And we can calculate SIV:

    SIV = 186.4 kV / √2 = 131.8 kV

    Therefore, the surge impedance loading at the circuit breaker terminal is 8.3 MW and the surge impedance voltage is 131.8 kV.
