Answer Posted / 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

What is the function of under voltage release ?
A 15 kw squirrel cage motor having a maximum efficiency of 90% on a continuous full load has temperature rise of 42 degrees celcius after 30 min and 52 degrees celcius after 1 hr under the above operation conditions. a) calculate its final steady state temperature rise on continuous load and the heating time constatnt. b) if the motor is operated on a short load for 9 min estimate its temperature rise. c) calculate the maximum overload that can be applied on a short, 9 min rating so that the temperature rise is the same as the final steady state temperature rise on continuous load.
