480 transformer to 120 ac current what is the kva on transfomer?
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.
Convert kva to full load amps?
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?"
Does a transformer convert the current from 240 volts to 120 volt?
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.
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.
Convert 2KW to KVA in single phase?
P=1.73xVxIxCOSO KVA=KW/1.73xCOSO KVA=2000/1.4 KVA=1.42
How can you convert the kva rating into kw rating?
kva*cos(phase angle)
How do you calculate kva to ampere?
You cannot convert them. KVA is a measure of power, while amperes are a measure of current.
How do you convert 208 v 2160 Amperes to KVA?
To convert amps to kVA, you use the following formula: Amps = (kVA x 1000 / voltage) / 1.73
How do you convert 110volts to kVA?
You must know the current or resistance to convert voltage to power.
How do you convert single phase kva to three phase kva?
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.
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 do you Convert va to kva?
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
How do you convert .19mva to kva?
Multiply by 1000. .19MVA = 190kVA
How do you convert 3000A to kva?
remove three 0s will do the trick
How do you convert kva to amps three phase system when you have 220-240 volts?
Amperes when kva is shown. The formula is, Amps = kva x 1000/1.73 x volts.
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.
