A three-phase AC system is a common method of distributing electrical power. It is widely used in industrial, commercial, and residential applications due to its efficiency and balanced power delivery. In a three-phase system, three sinusoidal voltage waveforms are generated, each with a phase separation of 120 degrees. These voltages are referred to as phases and are denoted as phase A, phase B, and phase C. features of a three-phase AC system include:
Three-phase generator: The power is typically generated by a three-phase alternator or generator. The generator produces three separate voltages, each with a phase difference of 120 degrees. This ensures a continuous and smooth power output.
Balanced loads: In a three-phase system, the loads are ideally balanced, meaning that the power drawn from each phase is equal. Balanced loads help distribute the power evenly across the system and minimize voltage drops.
