The formula to find amps is: I = (KVA x 1000)/(E x 1.73) I = (2500 x 1000) / (480 x 1.73) I = 2500000 / 830.4 I = 3010.597A
A voltage of 240 volts is not a common three phase voltage. Single phase kva of 240 voltas and 50 amps is I x E/1000 = 240 x 50 = 12000/1000 = 12 kVa -- Assuming the 240 volts is phase to phase voltage, and this is a three phase application: KVA = V*I*sqrt (3) = 20.78KVA
KVA means thousands (K) of volts (V) times Amperes (A). A 100 KVA transformer can deliver 1000 amps at 100 volts or 500 amps at 200 volts etc.
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.
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).
20.44 kva
The formula you are looking for is , A = kva x 1000/Volts.
It is apples and Oranges--kVA and volts are different units describing different things. Determining kVA requires measuring both voltage and current.
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.
Amperes when kva is shown. The formula is, Amps = kva x 1000/1.73 x volts.
12 volts
Amps * volts / 1000
To calculate the amperage in the secondary side of a transformer, you can use the formula: Amps = kVA / (Volts x Sqrt(3)). For a 250 kVA transformer with a 220-volt secondary, the amperage will be approximately 660.4 Amps.
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 = (0.001) times (Amperes) times (Volts)Kilowatts = (KVA) times (power factor)
For single phase,kva=voltage(volts)xcurrent(amps)/1000 For,three phase,kva=1.732xvoltsxamps/1000
Volts per hour is an invalid statement. You may have meant Watts per Hour.
