KVA means kilo volt amps or kilo Watts. A watt = 1 volt X 1 Amp. Kilo is shorthand for 1000. A watt is a measure of power, which is voltage x amps. Therefore it is not possible to relate voltage to KVA without additional information. Formula wise the above is correct but if you really need the voltage, it can be measured with a volt meter or VOM by putting the test leads across the output terminals of the KVA device.
To calculate the kVA rating of the transformer, you can use the formula: kVA = (Voltage × Current) / 1000. In this case, the secondary winding delivers 10 amps at 480 volts. Therefore, the kVA rating is (480 V × 10 A) / 1000 = 4.8 kVA.
KVA is a measure of power, while amp (or ampere) is a measure of current. KVA meanes kiloVoltAmps. 1 kVA = 1000 V*A. so 225 KVA = 225,000 VA (volts * amperes) So you would need to also know the voltage, in order to find the amperes.
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*cos(phase angle)
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.
It is apples and oranges--kVA and volts are different units describing different things. Determining kVA requires measuring both voltage and current.
Amperes when kva is shown. The formula is, Amps = kva x 1000/1.73 x volts.

Depends on the kva rating of the devices to be tested using a transformer.
the capacity of a transformer is defined as a product of voltage and current flowing through it.AS THE CURRENT IS MEASURED IN AMPERES AND VOLTAGE IN VOLTS, Hence transformers are measured/rated in KVA
To convert amps to kilovolt-amperes (kVA), you need to know the voltage level. The formula is kVA = (Amps × Volts) / 1000. For example, at 240 volts, 800 amps would equal 192 kVA, while at 480 volts, it would equal 384 kVA. Thus, the kVA value will vary depending on the voltage used in the calculation.
