Answer / amit khamesra

The purpose of VT and CVT in EHV system is same ie. to step
down the EHV to low voltage for measurement and protection
purpose. The extra function which CVT performs is to trap
the high voltage signals from the line which are used for
PLCC communication.

Answer / sukhvinder

Potential Transformer is designed for monitoring single-
phase and three-phase power line voltages in power metering
applications.

The primary terminals can be connected either in line-to-
line or in line-to-neutral configuration. Fused transformer
models are designated by a suffix of "F" for one fuse
or "FF" for two fuses.

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.

Answer / masood babar

the purpose of VT & CVT are same. but CVT use for High
Voltage line because we know high voltage surging can
disturbe your metering & protection accuracy so that reason
we use CCVT or CVT it has many capacitor to damp & stablize
all voltage during Surging and give smooth voltage.
