Which circuit type is typically characterized by three-phase power systems?

• A. Single-phase circuits
• B. Delta circuits
• C. Wye circuits
• D. Both Delta and Wye circuits

Answer: (D)

Three-phase power systems typically use two main configurations: Delta and Wye. Both of these configurations effectively handle three-phase power, allowing for efficient transmission and distribution of electricity. In a Delta circuit, the three phases are connected in a closed loop resembling a triangle, which enables the three-phase loads to share the total current and provide a balanced load. This configuration is commonly used for high-power applications because it can deliver more power at higher voltages. Conversely, a Wye circuit connects each of the three phases to a common central point, which can be either a transformer or neutral point. This configuration allows for lower voltage paths and is beneficial for grounding and supporting single-phase loads in conjunction with three-phase systems. Both Delta and Wye circuits are integral to three-phase systems, making them essential for various industrial and commercial power distribution networks. Therefore, the answer accurately reflects that both configurations are indeed associated with three-phase power systems.
