Answer Posted / jameel
the design of windings of transformer depend on the voltage
and current that is meaning kva .
morover the transformer hasnot mechanical output load such
as motor to say the power in kw.
only we calclate iron losses and copper losses in kw.
also the power factor in windings changes according to the
loads which connection in the secondary windings
usually trasformer and generator rated power in kva but the
motor in kw which is the useful power or active power.

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.
