In electrical engineering, three-phase electric power systems have at least three conductors carrying alternating voltages that are offset in time by one-third of the period. A three-phase system may be arranged in delta (∆) or star (Y) (also denoted as wye in some areas, as symbolically it is similar to the letter 'Y').
Here’s the 3-phase power equation: P (kW) = (I (Amps) × V (Volts) × PF × 1.732) ÷ 1,000. As we can see, the electrical power in the 3-phase AC circuit depends on: I (Amps): Electrical current, measured in amps. The more amps we have, the more power we have in a three-phase circuit. V (Volts): Electrical potential, measured in volts.
In this article, I will share with you how we calculate power step by step, and below I provide a power calculator. The formula for calculating the power in a three-phase electrical circuit is: P= √3 ×VL×IL×cos (θ) Where: P is the power in watts (W). is the line-to-line voltage in volts (V). is the line current in amperes (A).

It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer power. Three-phase electrical power was developed in the 1880s by several people.
25 lis 2010 · Electrical 3-phase equations. Most AC power today is produced and distributed as three-phase power where three sinusoidal voltages are generated out of phase with each other. With single-phase AC power there is only one single sinusoidal voltage.
To calculate the total power of a three-phase system, the formula used is as follows: Total Power (W) = √3 × Voltage (V) × Current (A) × Power Factor. This formula considers that the three-phase system has three separate phases, each with its own voltage and current.
