In a Wye connection (3-phase power), how are the coils connected?

In a Wye connection, also known as a star connection, the coils of the three-phase system are connected together at a common neutral point. This arrangement forms a 'Y' shape, where one end of each coil is connected to a neutral point, and the other ends are connected to the phase lines. By connecting the coils to a neutral, the Wye configuration allows for a balanced load, which can help manage voltage levels and provide stability within the circuit. The presence of the neutral point also enables the system to supply both single-phase power and three-phase power, making it versatile for various applications.

This configuration enhances safety and can minimize circuit imbalances, as any fault or imbalance in one phase can be managed through the neutral point. The design also effectively handles phase-to-ground faults, which adds further benefits to its usage in electrical systems.
