Phase Sequence Protection System Design & Simulation

Designed and simulated a specialized control circuit to protect 3-phase motors from Phase Sequence reversal, ensuring the motor only operates when the phase rotation is correct.

Technical Features:

Phase Sequence Monitoring: Integrated a Phase Sequence relay logic to detect the correct order of L1, L2, and L3.

Safety Interlock: The system automatically prevents the main contactor (M) from energizing if a fault or phase reversal is detected, protecting the mechanical load from rotating in the wrong direction.

Status Indicators: Included visual logic for "Normal" and "Fault" states.

Integrated Protection: Includes Thermal Overload (OL) and Emergency Stop for comprehensive motor safety.

Tools Used:

CADe_SIMU for electrical drafting and dynamic simulation
