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.
