The three phase calculator uses the power triangle in which Real Power is expressed in Watts (W). Reactive Power is expressed in Reactive Volt Amps (VAR). Apparent Power is expressed in Volt Amps (VA). With power in an AC system there is always an inductive or reactive aspect to the circuit which causes the current to lead or lag the voltage. The actual power draw from a circuit takes this into consideration and is described as Apparent Power. Three phase power means that each phase is 120 degrees out of phase with each other. The voltage between two lines is the line voltage. Three phase power is typically used for induction motors (as it helps reduce the need for a starter capacitor) and heavy loads because it is usually more economical that two-wire/single phase. Voltage availability is regional and is 50 or 60Hz. In both Delta and Star (or Wye) configurations the calculations for real/active, apparent, and reactive power are the same. Phase and line current are equal in the Star (or Wye) configuration, and the line voltage is equal to √3 times the phase voltage. In Delta configuration line and phase voltage are equal and line current √3 times the phase current.
