Is This Answer Correct ?    15 Yes 5 No

what is the purpose of CT,PT..

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

Is This Answer Correct ?    2 Yes 2 No

what is the purpose of CT,PT..

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.

Is This Answer Correct ?    7 Yes 8 No

what is the purpose of CT,PT..

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.

Is This Answer Correct ?    2 Yes 5 No

what is the purpose of CT,PT..

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.

Is This Answer Correct ?    3 Yes 7 No
