Resumen:
In recent years, important advances have been made in faults detection in rotating electrical machines through on-line and non-invasive techniques. Most of the proposed techniques are based on monitoring the stator voltages and currents or other variables estimated from them. Moreover, some of the proposed diagnostic tools have been able to detect mechanical faults in the powertrain that drives the motor, for example, in the coupling between the motor and load or in gearboxes. This paper presents a diagnostic case study of starters of wound rotor induction motors. Although a particular case detected in routine studies on a 5.4 MW motor is studied, the diagnostic proposal used can be extended to other similar cases. The diagnostic tool allows identifying faults in external rotor resistances, set the switching times of each resistance step, carry out the motor protection coordination and optimize the starting in order to cause the lowest possible motor temperature increase.
