Answer / zulfiquar
All the machines we are using like transformer, DG's are
all in KVA becoze at that particular time we dont know the
consumer power factor as we know (Active power= apparent
power x power factor) KW= KVA x Cos phi, that is why we
have machine in KVA rather the KW

Because DG set acting as a power source and supplying
to differnts loads .

Answer / subodh kumar
becouse alternatar have two type losses
1. iron losses
2. copper losses
so we find the iron losses in voltage & copper losses find
in amp that is why we take reating in KVA

Answer / tarkeshwar
As we know D.G. set i used to generate the Power . it
generate Active power & reactive power(Apperentus
Power=Active Power P+ j Reactive Power Q) and we consume
only active power(KW) that's why the DG rating is in KVA or
MVA, these are the unit of Aperantus Power

Answer / g c a
IN DG's load is decided by the users.... wheather it is
inuctive load or capacitve load......... so that's why
it's in KVA

Answer / stanley
In DG, the armature has conductor loss (Ia). it give output
voltage with conductor loss. Tth electrical loss is in Amps
(I). So kilo volt +Ampere=KVA

DEAR SIR, HOW TO CALCULATE WELDING TRANSFORMER CAPACITY IN KW OR KVA (POWER). TWO WELDING TRANSFORMER USED WHAT TYPE OF DG SET CAPACITY LIKE ( 45 KVA OR 62.5 KVA), PLEASE TELL THE WELDING TRANSFORMER RATEINGS. I AM REFINARY (TANKS WELDING) THANKING YOU
