4, How to draw how to drawing Star Delta stater power diagram

⚡ Star-Delta Starter Power Diagram – Description In this part of your AutoCAD Electrical practical, you will draw the power wiring diagram for a Star-Delta starter, which is used to reduce the high starting current of large 3-phase induction motors. 🎯 Objective: To show the main power connections between the motor, contactors, and power supply in star and delta configurations. 🧰 Key Components in the Power Diagram: 3-Phase Power Supply (R, Y, B) Main Contactor (K1) Star Contactor (K2) Delta Contactor (K3) Overload Relay (OLR) 3-Phase Induction Motor Fuses or MCBs 🔌 Power Wiring Flow: Power Source (R, Y, B) → to Main Contactor (K1) From K1, power goes to: OLR and then to Motor terminals U1, V1, W1 Star Contactor (K2) connects motor terminals U2, V2, W2 together (for star start) After timer delay, K2 opens, and Delta Contactor (K3) connects: U1 ↔ W2 V1 ↔ U2 W1 ↔ V2 (for delta run) ⚠️ Important Notes: Only one contactor (Star or Delta) must be ON at a time to prevent short circuit. Overload Relay should be connected to motor’s final output line. The motor has 6 terminals: U1, V1, W1 (line end) and U2, V2, W2 (star/delta end). 🖥️ AutoCAD Electrical Drawing Tips: Use 3-phase busbars at the top. Place contactors side-by-side and show line connections with correct line types. Clearly label: Contactors (K1, K2, K3) Motor terminals (U1–W2) Input lines (R, Y, B) Use wire numbers and cross-reference to the control diagram (from Practical 5) ✅ Final Output: Your power diagram should: Show all power lines from supply to motor Include safety (MCB, OLR) Be clean, labeled, and ladder-style (or horizontal bus) Instagram link https://www.instagram.com/basi.celect...
