A 132 kV, 50 Hz, 3-phase transmission line delivers a load of 50 MW at 0·8 p.f. lagging at the receiving end. The generalized constants of the transmission line are : = = 0.95∠1.4°, = 96∠78°, = 0.0015∠90° Find the voltage regulation of the line and charging current. Use the T model assuming a medium length transmission line.
