VAC means volts AC, and is a measure of the voltage in an AC circuit.
KVA means kilovolt-amperes, and is a measure of the power in a circuit. For a resistive load, KVA is the same as KW, or kilowatts.
The two terms are not related in that you can not compare one to another without also knowing the current flowing in the AC circuit. VAC * IAC = KVA, when all values are in RMS (not peak to neutral or peak to peak quantities).

What would the input current be for a 275 kva transformer with 2 phase of a 480 vac in and 120 vac at 20 amp output?

You have two devices that are rated at 230 VAC single ph and your supply voltage is 480 VAC 3 ph you need a 480 VAC 3 phase to 230 VAC three phase xfrmer how do you calculate the xfrmer size?
The transformer size is calculated by using the load current that is required on the secondary side of the transformer. This secondary current is multiplied by the secondary voltage times 1.73. This total is then divided by 1000 to give you KVA. KVA = I x E x 1.73/1000.
200 amp equals how much kva?
200 amps is equal to zero kva. To answer this question a voltage is needed.
How many kva in 14 amp?
There is appoximately zero kVA in 14amp, .5 volt AC.
600 volts is how many KVA?
It is apples and oranges--kVA and volts are different units describing different things. Determining kVA requires measuring both voltage and current.
37 kilowatta equals how many kVA?
kva and kw are related as KVA = (KW/PF) pf:power factor

What does 7.5 amps equal in in kva?
It equals zero without a voltage.
300kva equals amps?
To convert kVA to amps, you need to also know the voltage. If we assume a standard voltage of 480V, then 300 kVA would be approximately 360 amps. This is calculated by dividing the kVA by the voltage and then converting to amps using the formula: Amps = (kVA * 1000) / (1.732 * Volts) where 1.732 is the square root of 3.
How many va equal to kva?
1000 VA = 1 kva
Two and an half kva equals how many ampere?
To convert kVA to Amps, you need the voltage at which the calculation is being done. Without the voltage, the conversion cannot be accurately calculated.
How many VA equal 1 KVA?
1000 VA = 1 kva
What is kva formula?
KVA is very simple, it is the Volts x Amps of an AC circuit in units of 1000. For a single phase AC circuit VA = E x I. KVA = (ExI)/1000 So if you have 120 VAC and 15 A then: VA = 120 x 15 = 1800; KVA = 1800/1000 = 1.8 For 3 phase circuits we need to add the square of 3 (= 1.732) as a factor. VA = 1.732 x E x I and KVA = (1.732 x E x I)/1000 So if you have 480 VAC and 23 A then: VA = 1.732 x 480 x 23 = 19,121; KVA = 19,121/1000 = 19.1 Note that KVA is higher than KW (true power) in circuits that are not purely resistive. The vector difference of the two is "Power factor".
How many kva on 88.88 amps in 1phase secondary 230 volts?
20.44 kva
How many KVA is needed for a 200A panel?
To determine the KVA needed for a 200A panel, you can use the formula KVA = (Voltage x Amperage)/1000. Assuming a standard voltage of 120V, the KVA would be 24 KVA (120V x 200A / 1000 = 24 KVA).
