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 |
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.

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.
