When geneartor is running in poor lagging side power factor
its excitation current increases then it is running in
improved lagging side.Kindly tell me when gen is running in
leading side what will happen

Answer Posted / naveen
your question is confusing, specify lagging or leading.
if generator running in leading PF then increase exitating
to bring it to lagging region, because it is ment for
lagging power factor only
if it is running in leading then chances of generator
failure are more,but before that generator protection will
trip.

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.
