Answer / kaleem

current transformer is design to measure the output current of the generating transformer

potential transformer are design to measure the output voltage of the generating transformer

Answer / raji.g

current transformer :(CT)
it is an electrical device which is used to measure the
high current,
Potential Transformer(PT):
To measure the high voltage

Answer / ajith

ct is used to measure corresponding current and to provide protection against fault currents

pt is used only to measure the amount of voltage in a particular circuit

Answer / gurmurat

the main purpose behind using CT,pt is to prevent the circuits from overcurrent,undervoltages nd earth faults
they step up/down high values of currents and voltages under measurements into desired values which could be measured by available instruments.

Answer / k.prakashchandra

In case of HT and EHT,to get rid of high voltage.In case of
LT CT ,to reduce the size of the leads.

Answer / praveen kumar gupta

CT is a current instrment Transformer. It is used to
linearly step down the primary current as per the rated
current of controlling device attached with. It is used as
current sensor.

PT is a potential instrument transformer . It is used to
linearly step down the primary voltage as per the rated
voltage of controlling device attached with. It is used as
voltage sensor.

Answer / k.prakashchandra

To convert current and voltage to the desired values

Answer / k.prakashchandra

Another purpose of using CT & PT is to remove the presence
of high voltage

how we can select MCB ratings according to Voltages, Curves.
