Abstract: This paper proposes a method by which Electrical Faults of 3-Φ Induction Motors can be diagnosed by a Computer Monitoring the Stator Current. A Computer Monitoring Diagnosis based on the proposed methodology was based on the so-called Park's vector approach. The stator current park's vector pattern has been discerning between 'Healthy' and 'Faulty' 3-Φ Induction Motors. The results obtained from the experiment show that current Park's vector pattern of the healthy motor was a perfect circle. In contrast, current Park's vector pattern under faulty condition was elliptical. In this way, the short winding fault of the 3-Φ induction motor can be easily diagnosed by comparing Park's vector representation. This laboratory experiment proves the effectiveness of the park vector in monitoring induction machines with the help of computers.
