A three-phase transmission line transmits 50 MW at 0.8 power factor lagging at 132 kV. If the impedance of the transmission line is (40+j100), calculate the pu values of: Y (1) the base impedance (ii) the base current (iii) complex power, real power and reactive or VAR power, (iv) voltage, current, (v) impedance, resistance, and reactance. For the transmission line, assume MVAbase = 100 and kVbase = 132.
