Online Three-Phase Power Calculator

Three-phase electric power is the backbone of modern electrical grids. It is more efficient than single-phase power because it uses less conductor material to transmit the same amount of electrical power.

Formula:

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

Where,
P = Three Phase Power, V12 , V13 = Voltage, I2,I3 = Current, θ = Displacement Angle, cos = Cosine L1 L2 L3 3-Phase AC Voltage Cycle

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.
