True or False: The wye secondary must have the common or neutral point grounded.

The statement is true because in a wye (Y) configuration, the common point, or neutral, serves a critical role in the electrical system. Grounding the neutral point enhances safety by providing a low-resistance path to ground in case of a fault. This grounding helps to stabilize the voltage levels in the system, prevents the buildup of voltages that could be hazardous, and allows for reliable operation of protective devices.

In practical terms, grounding the neutral can minimize interference with sensitive equipment and reduce electromagnetic interference. By establishing a clear reference point for the phases of the system, it ensures that phase-to-neutral voltages remain consistent, facilitating efficient operation and protection measures.

While there may be contexts or specific configurations in which the grounding of a neutral might be addressed differently, for standard wye-connected systems, grounding the common point is a fundamental requirement for safety and operational integrity.
