Star vs Delta Connection Diagram

🌟 Star Connection vs 🔺 Delta Connection

Star Connection (Y):

• Each phase winding is connected to a common neutral point.
• Phase voltage = Line voltage ÷ √3.
• Used for starting motors with reduced voltage and current.
• Suitable for long-distance transmission due to lower current.

Delta Connection (Δ):

• Windings are connected end-to-end forming a closed loop.
• Phase voltage = Line voltage.
• Used for running motors at full load with high torque.
• Common in short-distance distribution and heavy-duty motors.

⚡ In short: Star → lower current, safe starting; Delta → higher power, efficient running.
