bus pt means bus potential trnsformer
it is used to measure the voltage in the bus and it is very important at the time of synchronising.

Answer / achita rao

IN SUBSTATION BUS PT ARE USED FOR MEASURIN HIGH VOLTAGE IN THE BUS

Answer / chetan

PT is a potential transformer which is use to meassuremet
or metering of voltages.

Answer / deadzg_devil

Because in power stations large current flows thru the
cables n for measurement of currents or any fault the
apparatus required must be highly rated n it wud be costly.
Therefore PT's are used to step down the current to lower
levels for measuring them
