How many degrees separate the phases of a 3-phase transformer system?

• A. 90 degrees
• B. 120 degrees
• C. 180 degrees
• D. 360 degrees

Answer: (B)

In a 3-phase transformer system, the phases are separated by 120 degrees. This 120-degree separation is a fundamental characteristic of 3-phase electrical systems, which ensures that the phases are evenly distributed over a complete cycle. This arrangement allows for a more constant power and efficient operation across the system since the combined power output from all phases remains steady. To elaborate, each phase in a 3-phase system reaches its peak voltage at different points in time. As one phase reaches its peak, the other two phases are at different stages of their cycles, providing continuous power delivery. This phase separation is crucial for balancing the load and optimizing the performance of the electrical system. In contrast, the other options represent angles that do not accurately reflect the phase relationships in a 3-phase system. For example, 90 degrees would imply an inadequate phase allocation, resulting in uneven power distribution, while 180 degrees would indicate two phases are perfectly out of sync, which is not feasible in a standard 3-phase configuration. A complete cycle of 360 degrees refers to a full rotation or cycle of a wave, which is not relevant when discussing the phase separation specifically within a 3-phase context. Hence, the correct and significant separation for a 3-phase
