Motor testing with MTO106

Motor testing with MTO106

Winding resistance measurements are conducted for detecting various faults in transformers – including shorted turns, loose connections, broken strands, and malfunctioning tap changer mechanisms. Winding resistance test sets such as the MTO106 are also capable of testing electric rotating machinery – motors and generators. Winding resistance measurements detect problems in a motor that other tests may not find. These problems include partial or fully shorted coils, poor crimps/connections, imbalance between phases (improper turns on a phase), and incorrect coil (phasing) connections.
