Three Phase Power Calculator

Calculate the Three Phase Power for given values.

Voltage V12 V
Current I2 A
Displacement Angle °
Voltage V13 V
Current I3 A



Three Phase Power W


P = ( V12 * I2 * cos ( 30 + θ ) ) + ( V13 * I3 * cos ( 30 - θ ) )


P = Three Phase Power,

V12 , V13 = Voltage,

I2,I3 = Current,

θ = Displacement Angle,

cos = Cosine

Three Phase Electric Power is basically a method of alternating current power generation, transmission, and distribution.It is the most common method used by elictrical grids to transfer power worldwide.Three-phase electricity is by its very nature a much smoother form of electricity than single-phase or two-phase power. It is this more consistent electrical power that allows machines to run more efficiently and last many years longer than their relative machines running on the other phases.Three-phase electric power systems have at least three conductors carrying alternating current voltages that are offset in time by one-third of the period.
