  1. 2068 BhadraChapter 3: Computational Technique3.2 Impedance and Reactance Diagram

    Draw a reactance diagram of the electric power system given below and express all reactance in per unit system by choosing appropriate base values.

    G: 14.kV [unclear], 30MVA, 10%

    M: 11kV, 25MVA, 13%

    $T_1$: 66/11kV, 25MVA, 12%

    $T_1$: 13.8/66kV, 25MVA, 12%

    Line: $j18\,\Omega/\text{phase}$
