how does the terminal voltage of transmission lines increase when a capacitor is connected???? This happens not only in transmission lines but also in all circuits. How??? When a capacitor is connected in a transmission line, capacitor also takes energy from the same supply. But how is it able to increase the terminal voltage??? Practically What sequence of events happen during increase in voltage???

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.
