True or False: A wye on both the high and low side must have a ground on the low side; however, the ground on the high side may be floated.

In power system configuration, particularly in transformer connections, it is essential to understand the grounding requirements. In a typical wye (or "Y") connection, grounding on the low voltage side is crucial for safety and system stability. This grounding provides a reference point for the system and helps protect personnel and equipment from electrical faults.

The necessity of grounding the low side is due to the fact that it acts as an effective return path for fault currents. When a fault occurs, having a ground connection helps clear the fault quickly, reducing the risk of equipment damage and enhancing safety for maintenance personnel.

On the other hand, the grounding of the high side can be more flexible. It can be "floated," which means it is not grounded but remains functional in the system. This configuration can help to prevent ground fault issues from affecting the high voltage system and allows for specific protective measures to be tailored to the system design and operational requirements.

Therefore, it is correct to state that a wye on the low side must have a ground, while the grounding on the high side may be floating, which is why this statement is evaluated as false. The requirements for grounding on both sides can vary based on system design and regulatory standards, but the primary objective remains safety and fault
