Answer / 7anoter4

Sheik answer is almost correct with some remarks:
Diesel Motor rating is in Horse Power [HP] since this is a
motor. The DG-Diesel Generator -the generator rating- is in
kVA [the actual [active] power depends on p.f. [cosfi] and it
is measured in kW indeed. This power is variable depending on
required –and produced power but the maximum will be for p.f.
=1.Then the kW=kVA .The rated power is the maximum output
power which in indefinite time will not damage the generator.

Answer / raja ganesh

In transformers and generator copper loss is depends on current and core loss is depends on voltage.so it is mentioned in KVA

Answer / sheikh

KVA is called Apparent Power and KVA is called active power
and such type equipment like Generator , Transformers.UPS etc rating shown in KVA.

i have one source transformer with the capacity of 50KVA, connected with two loads 10kw and second one is 15kw.. how can i calculate first load in KVA and second one in KVA .. because Kva rating, power factor rating of of transformer is different from the load… there must be some way to calculate load KVA rating and power factor….
