# Three Phase Power Calculator

Calculate the Three Phase Power for given values.

## Formula:

P = ( V_{12} * I_{2} * cos ( 30 + θ ) ) + ( V_{13} * I_{3} * cos ( 30 - θ ) )

**Where,**

P = Three Phase Power,

V_{12} , V_{13} = Voltage,

I_{2},I_{3} = 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.
