Star (Wye) vs. Delta Connection in Three-Phase Systems

Star (Wye) vs. Delta Connection in Three-Phase Systems

🔹 Star (Wye) Connection

Voltage: Line Voltage = √3 × Phase Voltage

Current: Line Current = Phase Current

Neutral: Yes, has a neutral point

Applications: Low-voltage systems, power distribution, motor starting

Advantages: Lower voltage, balanced load, suitable for 3-phase and single-phase loads

🔸 Delta Connection

Voltage: Line Voltage = Phase Voltage

Current: Line Current = √3 × Phase Current

Neutral: No neutral point

Applications: High-voltage systems, industrial motors, transformers

Advantages: Higher voltage, handles more power, no neutral required

▶️ In summary:

Star (Wye): Ideal for lower voltage, balanced loads with neutral.

Delta: Perfect for high-voltage, power-intensive applications.
