It is less confusing if we capitalize the units as required.
1 kVA = 1 kW, as originated from power [W] = current [A] * voltage [V].
The 'k' means 'times 1000'.
The statement can be re-written as 1000 VA = 1000 W.
multiply by the power factor and you will get the kW in single phase
P=1.73xVxIxCOSO KVA=KW/1.73xCOSO KVA=2000/1.4 KVA=1.42
1 tone = 1540 Watts=1.540 KW. whereas 1 KW=1.25 KVA. I think you have got the answer.
The KVAR will be 1249.75, the power factor is .7. KVAR = sqrt [ KVA^2 - kW^2 ]
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)
Formulas you need for single phase calculations. KVA = I x E/1000, KW = I x E x pf (where pf = power factor). For your question multiply the KVA by the power factor to get KW and then move the decimal point three places to the right to get watts. They are virtually the same. A watt is volts times amps. KVA is thousand of volts time amps. KVA and KW ratings are the same.
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
Multiply by Amps.
kva*cos(phase angle)
kVA = kW divided by (power factor). The power factor is the cosine of the angle between voltage and current.
P=1.73xVxIxCOSO KVA=KW/1.73xCOSO KVA=2000/1.4 KVA=1.42
5kw = 6.25 kva becoz kva = kw/ pf if we take pf is o.8
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.
KVA is the unit for the apparent power i.e it's the vector sum of the true power in KW and the reactive power in reactive volt-amperage. So, to get the value of the KVA for the 30KW,just divide the active power(30kw) with the power factor of that load.
kva and kw are related as KVA = (KW/PF) pf:power factor
To convert from KVA (kilovoltamperes) to KWH (kilowatthours) first convert to KW (kilowatts) by multiplying by power factor. Power factor is the cosine of the phase angle between voltage and current. Then multiply by the number of hours that you run the load.
You need to convert KVA to KW. In order to do this correctly you need to know your power factor.,
1 tone = 1540 Watts=1.540 KW. whereas 1 KW=1.25 KVA. I think you have got the answer.
