The kVA rating will be listed on the transformer's nameplate, which is usually on the front of the transformer. The 480v to 120v is irrelevant, because many transformers with different kVA ratings convert 480 volts to 120 volts. The kVA ratings can be different and thus affect the rated current through the transformer.
kva means 1000 x voltage x currentSo in order to determine the current we need to know the voltage.AnswerA kilovolt ampere (kV.A, not kva) is a measure of a circuit's apparent power, whereas the ampere(not amp) is a measure of current. These are two completely separate quantities, so your question is quite meaningless. You might have well have asked, "How metres are there in a kilogram of sugar?"
Transformers are rated in KVA or VA (volt-amps). They transform voltages from one value to another. The current in a transformer is inverse to the voltage. This is why transformers are rated in KVA and smaller ones in VA.
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.
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*cos(phase angle)
To convert from Amperes to kVA, you can use the formula kVA = (Voltage x Amperes) / 1000. Plugging in the values, kVA = (208 V x 2160 A) / 1000 = 449.28 kVA.
You cannot convert them. KVA is a measure of power, while amperes are a measure of current.
a kva is 1000 vaK is kilo, which means 1000 similar to how a kilometer is 1000 metersTransformers are usually rated in KVA, so a 45 KVA Transformer is a 45 000 VA Transformer
Va=volts x amps. The K stands for one thousand. So 1 Kva is one thousand watts. So 415v times 120a= 49,800 what's. You divide that by a thousand and you get 49.8. So it would be 49.8 Kva.
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.
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
You must know the current or resistance to convert voltage to power.
Multiply by 1000. .19MVA = 190kVA

Amperes when kva is shown. The formula is, Amps = kva x 1000/1.73 x volts.
To convert 110 kVA at 440 volts to amperes, you can use the formula: Amperes = kVA / (Volts x 1.73) for three-phase systems. In this case, 110 kVA / (440 volts x 1.73) ≈ 143.37 amperes.
