How many degrees apart are the phases in a three-phase power system?

In a three-phase power system, the phases are distributed evenly across a complete cycle of 360 degrees. Since there are three phases, each phase is separated by an equal angle, which is calculated by dividing the total degrees of the cycle (360 degrees) by the number of phases (3). This results in each phase being 120 degrees apart from the next.

This configuration allows for a balanced and efficient distribution of power, as it ensures that the peaks and troughs of the current in each phase occur in a staggered fashion. Consequently, this arrangement helps in maintaining a consistent supply of electricity and stabilizes the load on the electrical system.

Understanding this 120-degree separation is key to grasping how three-phase systems work, as it directly impacts the performance and stability of three-phase motors and generators.
