Answer Posted / tapan k ghosh
The output expected from a generator or transformer is
electrical output. Electrical output contains both active
and reactive components and hence these equipment are rated
in terms of composite power,kVA i.e.sqrt(active2+reactive2).
Output expected from a motor is motive power i.e. active
one and hence motor is rated as kW.
