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
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
Convert kw single phase to 3 phase kva?
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.
How many kva is 21000 kw?
KVA is the vector sum of real and reactive power; put differently, KVA at a specified power factor will tell you how many KW you have: KW = KVA * pf You must provide a power factor or power factor angle (if angle, replace pf with cos (pf) in above equation) or total reactive power to calculate.
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
37 kilowatta equals how many kVA?
kva and kw are related as KVA = (KW/PF) pf:power factor

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.
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.
How can you convert the kva rating into kw rating?
kva*cos(phase angle)
Convert 2KW to KVA in single phase?
P=1.73xVxIxCOSO KVA=KW/1.73xCOSO KVA=2000/1.4 KVA=1.42
What is the KVAR if kva is 1750 and kw is 1225?
The KVAR will be 1249.75, the power factor is .7. KVAR = sqrt [ KVA^2 - kW^2 ]
How do you calculate DG set current from kva?
Rating for DG set and any of electrical machines is calculated in KVA. KVA is calculated as KW/pf. One can calculate the required KVA for DG set with this formulation: (KW/pf)/load rate. For example KW=110, pf=0.8 and one loads the DG at 75%, so KVA= (110/0.8)/0.75=185 KVA.
Convert 5.0KW to KVA?
5kw = 6.25 kva becoz kva = kw/ pf if we take pf is o.8
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)
