PT-Potential transformer
CVT- coupling(capacitor) voltage tr

Answer / khilendra pant

EMVT:-Electromegnetic voltage transformer.

PT:-Potential transformer.

CVT:-Capacitor voltage transformer.

Answer / j. ramanath

CVT which is also called (CCVT) capacitor coupled voltage
transformer which is used to reduce the voltage from 400 KV
and higher to 110 volts for the purpose of deriving
metering, relaying and protection signals. Here the high
voltage is applied across two capacitors in series with an
inductor in parallel of these capacitors which form the
primary winding of CVT. The secondary winding terminals at
different tapping points are brought out to a small junction
box mounted on the base of the equipment from where it is
wired for different functions

Answer / biswa ranjan lenka

EMVT- for protection only(accuracy is very high)
CVT- both metering and protection
P.T- both

P.T uses winding for step down the voltage
CVT- uses two capacitor in series(capacitor coupling) to
step down the voltage

Answer / jugal soni

PT is a potential transformer which use to measuring a voltage
EMVT is same as the PT both are the use for the volage
measuring but accuracy is high of the EMVT.
CVT is voltage transformer but it works on capacitance. and
it is also used for the PLCC.

Grounding. Dear all at one of my site we checked the amps at the earthing cable to the alternator it was found 125 to 130 A. at the neutal cable in same machine found 146A. in the same plant checked the earthing current on other alternator it was 52A, and neutral 116 A. we are facing problems with our controller and the card was damaged once. can that neutral/GND current be a reason? as there is common grounding for the Alternator,Brkr panel,Transformer?
