Three Phase Transformer Calculator

I Want to Calculate

Effortlessly ascertain your three-phase transformer’s necessary volts, kVA, and amps.

Utilize our online Three-Phase Transformer Calculator to compute the current across different power units. Transformers are employed to elevate or diminish alternating voltage in electrical power. There exist two primary types: single-phase and three-phase transformers. A three-phase transformer comprises three intertwined magnetic circuits, facilitating an even dispersion of dielectric flux between high and low-voltage windings. Uncover the voltage, kVA, and amps of a transformer effortlessly through the utility of our user-friendly transformer capacity calculator.

Three Phase Transformer formula

    \[V = \frac{k \times 1000}{A \times Ph}\]

    \[A = \frac{k \times 1000}{V \times Ph}\]

    \[k = \frac{Ph \times V \times A}{1000}\]


  • V = Volt
  • A = Amps
  • k = kVA
  • Ph = 3 phase (√3 = 1.732050808)
