The simple formula to calculate the rating of three phase Transformers is: KVA = (√3. Kilowatts (kW) measure the real power in an electrical circuit, while kilovolt-amps (kVA) measure the apparent power. To calculate the kVA we need to know at least the line-to-line voltage (V) requirement of the load and the maximum load phase current (I). There-phase power calculation: How to Convert KW to kVA. We also use third-party cookies that help us analyze and understand how you use this website. Do you want to convert kVA to kW instead?. Current (I): Enter the the current in Amperes (A). FORMULAS USED IN CALCULATOR: 1-Phase KVA = Volts x Amps / 1000 1-Phase Amps = KVA / Volts x 1000 3-Phase KVA = Volts x Amps x 1.732 / 1000 3-Phase Amps = KVA / Volts / 1.732 x 1000 Arrange a Call Back. 3 >> Enter two value fine mitching value.

FORMULAS USED IN CALCULATOR: 1-Phase KVA = Volts x Amps / 1000 1-Phase Amps = KVA / Volts x 1000 3-Phase KVA = Volts x Amps x 1.732 / 1000 3-Phase Amps = KVA / Volts / 1.732 x 1000 the name plate on the transformer and my math both come up with 540 amp capacity. L1-L2: 390V. Request a Quotation. Calculations could be kVA from Amps and Volts, Amps from kVA and Volts or Volts from kVA and Amps. Calculation of Single phase amps to kVA S (kVA) = I (A) x V (V) / 1000, which means that the apparent power in Kilovolt-amps is calculated by multiplying the current in amps with the voltage in volts and dividing the results by 1000. Where: S (kVA) = Kilovolt-Amps. FLA - "Full Load Amps" - amount of current drawn when full-load torque and horsepower is … To calculate Kilovolt-amps (kVA), select single phase or three phase connection from the drop down, and convert the KVA calculation for Volts (V) and Amps (A). I Want to Calculate. Amperes - Enter the maximum current in amps that will flow through the circuit. It is the apparent power we wish to find. One kilo-volt-ampere is exactly equal to 1000 volt-ampere.
