the potential transformer is used for meetering purpose ,it
is a instrumental transformer it receives a high input but
sends a 110v only for meetering and relay purpose.but incase
of transformer it works step up/down

why the difference arise between HT reading & LT reading (submeters fixed in complexes, apartments etc)if the power factos exceed from 0.9 to 1 can the ht meter reads fast?
