why the rating of dc generator is in kw where as rating of
alternator is in kva?
Answer Posted / ramdarkmaster
In case of D.C generator it is supplying only active power(Kw) because the no capacitance or inductance loads connected to D.C generator, it's purely resistive. but in case of alternator it supplying inductive as well as capacitative load hence there are both active power(Kw) and reactive power(Kvar) and both combined together real power(KVA), hence alternator ratings are in KVA's.

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.
