Answer / sendhil

it is a potential transformer which is used for measuring
and protection of bus it is known as bus pt

Answer / giri

Bus pt senses voltage of the bus bar,it's used for
undervoltage protection,synchronisation during
autochangeover.

Answer / rajeev

a bus pt can be used for synchronisation purposes as well

Answer / vinayak

Bus pt is used for measure the voltage in bus and its
measure high voltage.

Answer / umesh kumar singh

Bus pt is a transformer whose function is measuring and
controling the relay panel,protection of bus from
undervoltage,over voltage.

Answer / anbarasan

Bus potential transformer function was measuring and
monitoring and protection purpose use.
one PT we have to use different applications possible.

Answer / kanupriya

It is used in transmission lines to avoid the complete
shutdown, we sectionalise the main bus by providing single
phase PT for synchronisation in case the transmission lines
has more than 8bays

Answer / sareer ahmad

Bus PT means Bus potential transformer either it can be CVT
or just PT.Its function is to measure the voltage and
current.It can also be used for protection purpose,that we
give differential protection for busses so we can connect
the secondary of bus pt to the relay.
