An artificial immune system approach for fault detection in the stator and rotor circuits of induction machines

Online computational tools dedicated to the detection of induction machine faults

“…The spectrum given by (15) shows that the calculation of the negative sequence current I À1 inevitably involves the calculation of the positive components sequences for k = 1,. . .…”

“…Recent advances and new techniques have been reported in the literature concerning calculation of faults in electrical machines these are; Multidimensional demodulation techniques for diagnosis of induction motors faults [11], polynomial-phase transform of the current for diagnosis of three-phase electrical machines [12], symmetrical components and current Concordia of an induction motor by feature pattern extraction method and radar analysis [13], Monte Carlo approach for calculating the thermal lifetime of transformer insulation [14], intelligent approach by an artificial immune system for the detection of induction machines faults [15], independent component analysis for fault detection and diagnosis of turbine [16], signature analysis for fault diagnosis of mixed eccentricity [17].…”

Analysis of rotor and stator winding inter-turn faults in WRIM using simulated MEC model and experimental results

“…Up to now, many papers have been published on modeling of squirrel cage induction motors with stator winding fault and broken bar conditions and/or fault diagnosis methods [6][7][8][9][10]. However, about modeling of WRIMs, there are not sufficient investigations, especially on inter-turn short circuit fault in rotor windings.…”

Diagnosis of stator winding short circuit faults in a direct torque controlled interior permanent magnet synchronous motor

“…The adverse conditions of heat will occasionally lead to the progressive deterioration, and eventual breakdown of the winding insulation in a phase of the motor [5], [6].Therefore an early detection of inter-turn short during motor operation is quite important to avoid subsequent damage to adjacent coils and stator core, which reduces repair cost and motor outage time. Many works have been reported in the literature on fault detecting and diagnosis in stator winding [7]- [13]. In [11], the authors proposed two different approaches for diagnosis of the fault.…”
