Yes, if the power factor (cosine of the phase-angle between voltage and current)
is ' 1 '. In order for that to be true, the total load impedances on the line have to
be pure resistive, with zero reactance.
All of this stuff applies only on an AC line. On a DC line, voltage and current are
always in phase, the power factor is 1, and KVA = KW .

Is 6.5kW greater generator than 6.5 kva generator?
Yes of cours1 kw =1.25 kva wich mean6.5 kw =8.12 kvaif you have generator 8.12 kva it give you 6.5 kw=============================Answer #2:1 kw does not necessarily = 1.25 kvaThe relationship between KW and KVA depends on the nature of the load you'repowering, and is called the "power factor". It describes how closely the voltageand current peaks coincide in time. If the load has any inductive or capacitxivereactance, then the voltage and current waveforms become separated in time.The "KVA" is the product of the full voltage and full current without regard fortheir "phase difference", but the "real" power in KW is the KVA multiplied by thecosine 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 thevoltage 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 orthe line, then your 6.5 KVA generator can just exactly supply 6.5 KW of load, withnothing to spare. More commonly, of course, a generator with somewhat morethan 6.5 KVA capacity is required in order to supply 6.5 KW of 'real' power.
In single phase 1 TR equals how many KW?
1TR = 3.5KW in Single phase and 1.2KW in 3-phase
What does 6 kw mean?
6 kw means "six kilowatts" or 6,000 watts. That in turn means "6,000 joules of energy every second".
Is wiseman Daniel emelandu of scoan have a wife?
I realy dnt kw
How many kilowatts does a 1.5 hp ac consume in one hour?
1.1 kW-hours
How do you change ac tonnage to kva and kw?
1 tone = 1540 Watts=1.540 KW. whereas 1 KW=1.25 KVA. I think you have got the answer.
37 kilowatta equals how many kVA?
kva and kw are related as KVA = (KW/PF) pf:power factor
Convert 800kvar to kw?
The same way, as you convert Appels to Carrots ........... There is a formula: KVAr = KVA / KW or cos=KW/KVA > Yes, we are treating KW, KVA, & KVAr as the 3 sides in a 90 deg TRIANGLE ! KW= vertical katede KVAr = horizontal katede KVA = hypotenuse
1 12hp motor takes what kva?
12HP is approximately 10.8 KVA. You would want to use a 15KVA transformer to supply this motor. KW = HP * .75 KVA = KW * 1.2 (These formulas are approximate)
Show solution of conversion of 1KVA to watts.?
1kva means 1kv per ampere therefore 1 amp flowing and 1 kv deduce to be the product of the two or 1kw
How many BTU is 3 KW?
The answer: 17070 BTU The math: 3414 BTU = 1 KVA (KW) so 5 KVA = 17070 BTU
How many kVA equal kvar?
For normal power factors (pf=80%), you have 0.8 kW for every kva. In general however, kW = pf x kVA. Where pf is the power factor, it is the cosine of the angular difference between the voltage and the current of a circuit in alternating current circuits.
How do we Calculate Kwh to Kvah?
To convert 'kwh' to 'kvah' you first need to measure the length of time. You will then convert this amount to hours by dividing by 3,600. You will then divide this amount by the length of time.
How many kva is equal to 1 kw?
It depends on the power factor, which you did not specify. Power factor is the ratio of true vs apparent power. KVA * PF = KW. Please restate the question.
Which is to consider in sizing generator kva or kw ratins?
the unit of generators power is KVA becoze the kva is the power that contain the active power (KW) and the reactive power mean that the name plate of any generator must contain the rated kva of it (like the transformer P (KW) = P (kva) * cos fi P (KW) = V I cos fi for single phase P (KVA) = V I when cos fi closed to 1 this will increase the useful power that exit from the generator or transformer with my pleasure
How to convert from kV into kW?
Multiply by Amps.
How do convert KVA to KW?
kVA = kW divided by (power factor). The power factor is the cosine of the angle between voltage and current.
