Answer Posted / amit rajak
Power factor is the cosine of angle between the current and
the voltage
by leading power factor we mean that the current is leading
the voltage by some angle
or simply current is more than the voltage.
and when it happens there is some losses that actually
occuring in the transmission or distribution system which
will effect the efficiency of the transmission of the power
supply system.

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.
