Classify transmission line model. Find $A, B, C, D$ parameters of short transmission line and also draw its phasor diagram with lagging and leading power factor of the load.
Draw the phasor diagram for a nominal ‘Tee’ circuit of a transmission line for lagging condition and find its $A, B, C, D$ parameters.
A 280 km long transmission line on a 60 Hz system has line impedance of $(33+j104)$ a total shunt admittance of $10^{-3}$ mho. The receiving end feeds a load of 80 MW at 220 kV at 0.8 p.f. lagging. Find sending-end voltage, current, power and power factor using (i) & (ii) and comment on results. (i) Nominal pi method (ii) Long lines
