Breakdown of the motor in the tap changer because of over voltage or miss-use also causes the tap changer to fail to change the turn ratio of the winding. 4. Core failure . The transformers have laminated steel cores in the middle surrounded by the transformer windings.
Electric Motor Problems & Diagnostic Techniques
www.emerson.comIf the motor keeps running with stator faults, a high current will flow through the windings where the problem is located. This high current generates heat which further degrades winding insulation and causes short-circuit between the windings and eventually products a phase-to-ground failure. The motor will fail quickly after that.
