We have to supply the power to the grid. So there is a capacitance is developed due to the high voltage lines and the earth surface. so in turn the voltage will increase till it reaches to the grid so maintain the required voltage we transmit it at a lagging power factor.

3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
