In a three-phase generator, the phases are displaced by how many degrees?

• A. 90 degrees
• B. 120 degrees
• C. 180 degrees
• D. 240 degrees

Answer: (B)

In a three-phase generator, the phases are separated by 120 degrees. This arrangement allows for a balanced load and consistent power delivery, which is a critical feature of three-phase systems. Each phase reaches its peak value at intervals spaced 120 degrees apart, resulting in a smooth and continuous power output. This 120-degree phase displacement enables the generator to utilize the full power potential by providing three alternating currents that are out of sync with each other. The advantage of this setup is that as one phase reaches its maximum output, the others are at a different point in their cycle, which helps maintain a stable and continuous energy supply. Thus, the generator can provide more power than a single-phase system and is more efficient for many industrial and large-scale applications.
