PT we are using at low voltgae and CVT we are using at EHV
line , CVT has more accuracy than PT
capacitor divider drop the voltage

Answer / abhishek

CVT means capacitive voltage transformer which is connected
between the lightening arrester and CT,which is used to
measure the voltage in the line in higher ratings,PT is
connected at the end of the bus bar system which is also
used to measure the voltage.

Answer / ramesh

PT is only for measure the voltage. CVT is only for
communication purpose

When capacitor bank connect on line. It's draw some current but it's current not increase of main line ammeter. Why?
