Why the wave trap is put in Y phse only in switchyard?why
not in other phases?

Answer Posted / prakash dewangan

Because Y phase is less prone to faults. B phase is prone
to earth fault and R phase is prone to lightning. So Y
phase is more safe for wave trap.

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.
