This case study descripbes thes process of diagnosticin and repravirin a faulty AC motor circuit in an industrial setting. It highlights common issues and troubleshooting steps used by technicans to restitue proper operation.

Inicial Symptomy a d Inspection

Te motor was experiencing intermitent operation, with frequent tripping of the circuit breaker. Visual securition requialed signs of overheating and burnt wiring connections near the contactor and motor terminals.

Electrical Testing and Diagnosis

Technicians perfored voltage and continuity tests. They confirmed that the contactor was receiving voltage but observed that that that thate motor windings showed high resistance, indicating possible insulation fagure. Thee motor 's thermal protection switch was also tested and spalocd to bee malfunctioning.

Identified Issues and Repairs

Te root causes identified included damaged motor windings and a faulty thermal switch. Repairs involved substitug thae motor with a new unit and installing a new thermal overshand protector. Additionally, damaged wiring was substitud, and connections were tienged to prevent overheating.
