Is 6.5kW greater generator than 6.5 kva generator?

Answer 1

Yes of cours

1 kw =1.25 kva wich mean

6.5 kw =8.12 kva

if you have generator 8.12 kva it give you 6.5 kw

=============================

Answer #2:

1 kw does not necessarily = 1.25 kva

The relationship between KW and KVA depends on the nature of the load you're

powering, and is called the "power factor". It describes how closely the voltage

and current peaks coincide in time. If the load has any inductive or capacitxive

reactance, then the voltage and current waveforms become separated in time.

The "KVA" is the product of the full voltage and full current without regard for

their "phase difference", but the "real" power in KW is the KVA multiplied by the

cosine of the phase angle. So if there's any inductance or capacitance present,

then the KW is less than the KVA. But if the load is pure resistive, then the

voltage and current on the line are in phase, the angle between them is zero,

and the KW and KVA are equal.

When everything is just exactly perfect, and there is no reactance on the load or

the line, then your 6.5 KVA generator can just exactly supply 6.5 KW of load, with

nothing to spare. More commonly, of course, a generator with somewhat more

than 6.5 KVA capacity is required in order to supply 6.5 KW of 'real' power.
