Three-phase power refers to:

Three-phase power refers to a type of power transmission that utilizes three alternating currents, which are offset in time by one-third of a cycle (120 degrees apart), providing a more efficient and stable supply of electricity. This arrangement allows for a continuous flow of power, as at least one of the phases is always at or near its peak voltage.

In three-phase systems, the electricity can be transmitted over long distances with lower losses compared to single-phase systems. This configuration is widely used in industrial settings because it can efficiently power heavy machinery and motors, making it essential in various applications.

Three-phase power systems are also capable of providing both balanced and unbalanced loads more effectively, enhancing motor performance and overall system reliability. Therefore, it is recognized as a vital component of electrical power systems, especially in commercial and industrial sectors.
