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 much kw in ikva?
Do you mean 1 kVA? kVA (thousands of volt-ampere) is the same as kW (thousands of watt) - assuming the current and the voltage are in phase (in other words, assuming the power factor is equal to 1), which is usually a good approximation.
Why transformers are tated in kva but not kw?
Because it is the current rating of the windings that determine the maxium load current, and the product of rated current and rated voltage, in a.c., is apparent power (in volt amperes), nottrue power (in watts).And, incidentally, the correct symbols are kV.A and kW, not kva and kw.
How do you compute ampere if the given is kvA kW power factor and voltage?
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)
37 kilowatta equals how many kVA?
kva and kw are related as KVA = (KW/PF) pf:power factor
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.
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.
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.
Why transformer are rated in kVA instead of KW?
Transformers are rated in VA or kVA. That is because the voltage is limited by the power loss in the magnetic core, and the current is limited by the power loss in the resistance of the windings. The rated voltage times the rated current gives the transformer's rating in kVA.
How do you change ac tonnage to kva and kw?
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.
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.
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
