Answer / rohit butala

CT i.e. Current Transformer, is used to sense the current
flowing through a conductor. Resister can be connected at
the secondary winding of CT, to get the voltage proportion
to the primary current. It can be used in the feed back
circuit to limit the current at the output.

Answer / sambi reddy

ct means current transformer. it is used for limit the
current in circuit.(ex- it is used in current limitting
circuit.

Answer / raj chakraborty

CT-current transformer is used to measure the amount of
current having huge range.
like 2500:5 CT will give o/p of 5 amperes for i/p of 2500
amperes.
so, the huge amount of current can be measured in this
indirect method, as the CT gives proportional o/p for input
current to be measured.

Answer / vipin sharma

it step down the amount of current in small ratio.,
such as 50:5. o/p, i=1; if 1f i/p, i= 10.it used in
measuremet and for protection purpose
