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.
use 1.0 as your PF Understand that K=1000, so KVA simply means thousands of volts times amps. First, multiply KVA by 1000 to get VA, then divide by the voltage of the system to get amps. Example: 6KVA, 240V single-phase. 6 * 1000 = 6000 VA 6000 / 240 = 25A
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
10 HP is 7.46 kW theoretically, but allowing for an 0.7 power factor the kVA goes up to 10.5 kVA. Add 20% for sundry losses and you get 12.5 kVA
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
Some confusion hereKW and KVA are units of power. The ampere is a unit of current. If you divide power by the voltage involved, you can determine the current involved, in amps. Power (watts) = volts x ampsA volt-amp is a watt. (A volt times an amp is a watt.)I=(KVA*1000)/(1.732*V) (Three Phase)AMP=KW/1000*V*PF--------------------------------------------------------------------------------------------------------------KW or KVA can be converted to one another but you cannot convert them to amps. You can compute amps by using this formula,KW = I x V x 1.732 x P.F/1000 (Three phase)KVA = I x V x 1.732/1000 (Three phase)
To convert 2 kW to kVA in single phase, you need to know the power factor. If we assume a power factor of 0.8 (common for many single-phase loads), the conversion formula is kVA = kW / power factor. Therefore, for 2 kW at a power factor of 0.8, the result would be 2 kVA / 0.8 = 2.5 kVA.
kva*cos(phase angle)
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.

No, it is not possible to convert a 2.4 kw single phase appliance to a 9kw 3 phase appliance. Single phase can not be converted to three phase with out considerable cost involved.

KW is multiplication of KVA and power factor. Power factor is load dependent and varies as per the type of load. Hence the rating or capacity is mentioned in KVA not in KW
Multiply by Amps.
kVA = kW divided by (power factor). The power factor is the cosine of the angle between voltage and current.
To convert AC tonnage to kVA and kW, use the following formulas: For kVA: kVA = (tonnage x 3.517) For kW: kW = (tonnage x 3.517 x power factor). Remember to consider the power factor of the system when converting from tonnage to kVA and kW.
5kw = 6.25 kva becoz kva = kw/ pf if we take pf is o.8
10 HP is 7.46 kW theoretically, but allowing for an 0.7 power factor the kVA goes up to 10.5 kVA. Add 20% for sundry losses and you get 12.5 kVA
