A polyphase system is an electrical system that uses multiple alternating currents (AC) that are out of phase with each other. The most common type is the three-phase system, which consists of three currents that are 120 degrees apart. This configuration allows for more efficient power transmission and distribution, reducing energy losses and improving the performance of electrical machines. In a polyphase system, the combined effect of the multiple phases results in a smoother and more constant power supply. This is particularly beneficial for industrial applications, where large motors and heavy machinery, such as those found in manufacturing plants, require reliable and efficient energy sources to operate effectively.
