In a wye-connected polyphase system, what is the common point referred to as?

In a wye-connected polyphase system, the common point where all three phases meet is referred to as the star point. This terminology is derived from the configuration of the connections, which resemble a star when visually represented. The star point serves as the neutral point for the system, providing a return path for current and allowing for the balance of the phases.

The star point plays a crucial role in ensuring that voltage levels are stable across each phase, and it allows for the use of neutral conductors in electrical systems. This is important for ensuring safety and reliability in power distribution. Additionally, it enables connections to be made to single-phase loads effectively when they are required.

The other terms mentioned can be misleading or not commonly used in this context. While "neutral point" can refer to the same concept in specific applications, "star point" is the standardized term used in discussions about wye configurations. The terms "access point" and "phase point" do not accurately describe the function or arrangement of the connections in a wye system.
