Convert a 10% transformer reactance from 20 MVA, 132 kV to 100 MVA, 132 kV → ( Z_pu,new = 0.1 \times (1)^2 \times (100/20) = 0.5 ) pu. 3. Transmission Line Parameters (PPT Module 3) Resistance: ( R = \rho \fraclA ) (corrected for skin effect at 50/60 Hz). Derived bases: [ I_base = \fracS_base\sqrt3 V_base, \quad

[ C = \frac2\pi \epsilon_0\ln(D/r) \ \textF/m ] new = Z_pu

[ \textpu value = \frac\textActual value\textBase value ]
