Answer / p krishna teja
A current transformer (CT) is used for measurement of
electric currents.Current transformers are commonly used in
metering and protective relays in the electrical power
industry.
A capacitor voltage transformer (CVT), or capacitance
coupled voltage transformer (CCVT) is a transformer used in
power systems to step down extra high voltage signals and
provide a low voltage signal, for measurement or to operate
a protective relay. In its most basic form the device
consists of three parts: two capacitors across which the
transmission line signal is split, an inductive element to
tune the device to the line frequency, and a transformer to
isolate and further step down the voltage for the
instrumentation or protective relay.

Answer / saadsms
CT:
This means current transformer converts current from high
values ​​to the value of 5 amps of output circuits for the
operation of measurement and warning devices, or any need of
this type...
CVT:
This means that there are two transformers together in the
same device is used for high voltage circuits
One-volt transformer and the other current transformer.
In the same container (one device).
