Is voltage & potential transformer are the same? Are they
used for same application ?

Answer Posted / sewagudde

VT and PT are the same thing. they step down high voltages
(132kV,33kv, 11kV etc) to a nominal value usually 110v
which is used to energize substation instruments such as
protective relays.importance of this is not to have bulky
relays which can withstand high voltages.

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.
