When using a wye secondary on any bank, what should be done with the neutral?

When using a wye secondary on any bank, the neutral should be solidly grounded to ensure the safety and reliability of the electrical system. Grounding the neutral serves several important purposes. It provides a reference point for the system voltage, which helps in maintaining stable voltage levels across the phases. Solid grounding also helps in the protection of equipment by allowing fault currents to return safely to the ground, thus facilitating the operation of protective devices like circuit breakers or fuses.

In a wye configuration, the neutral serves as a pathway for unbalanced loads, and grounding it effectively minimizes the risk of electrical shock and equipment damage during fault conditions. This practice is essential in various applications involving three-phase systems to ensure compliance with electrical safety standards and to safeguard both personnel and property from electrical hazards.
