Best Answer

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.

KVA=√ (KVAR2 + KW2)

So, KVAR = √(KVA2 - KW2)

We know KW = KVA cos Φ

=> KVAR = √(KVA2 - KVA2cos2Φ ) = √KVA2(1- cos2Φ) = √KVA2(sin2Φ) = KVA sinΦ

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


How calculate kvar if p is 560 kw and kva is 700?

The formula is that kW^2 + kVAR^2 equals kVA^2 or if you prefer, the kW and the kVAR are the two sides of a right angled triangle and the kVA is the hypotenuse. So here you have a 3-4-5 triangle times 140, in other words 420-560-700, and the kVAR is 420.


What is Kvr?

kV is kilovolts, kW is kilowatts, kVA is kilovolt amps and kVAR is kilovolt-amps reactive. A common formula is kVA-squared = kW-squared + kVAR-squared.

How many watts make 1 kva?

0 - 1000. KVA times a power factor gives you kilowatts, 1000 x watts. If the power factor is 0, then o watts make up your one kVA; if the power factor is 1, then 1000 watts make up your one kVA. Typical power factor is in the range of .8 to 1.

How many KW is in 150 KVA?

It depends on the power factor, which depends on the reactance of the load.For a typical power factor of 0.92, 150 KVAR translates to 383 KVA, which translates to 352 KW.Power factor is the cosine of the phase angle (theta) between voltage and current. KVA times cosine (theta) is KW, while KVA times sine (theta) is KVAR.
