“…It is to be noted that the effect of the shorted turns is to reduce the effective number of turns in the winding and, consequently, the effective impedance (Equations 4 and 5). 10,11 According to Liu et al 32 and from the experimental waveforms depicted in Section 4 of this paper, it is seen that when an inter‐turn fault occurs, the current amplitude of two phases is higher (including the faulty phase) than that of the other phase.…”

“…The three-phase motor parameters used for SITF detection with the proposed algorithm are measured by performing the no-load (NL) test, blocked rotor test, and direct current (DC) resistance test and winding resistance measurement at shutdown on the experimental motor. 32 The maximum stator winding resistances at a particular load condition can be measured just after shutdown of a motor in order to take into account the effect of the temperature rise. The rotor resistances referred to stator-side are then computed based on the DC resistance test, blocked rotor test, and the stator winding resistances measured at a particular load.…”

“…In the scientific literature, motor current signature analysis (MCSA) and vibration analysis are the most widely utilized techniques. Based on these signals, the design of an IM emulator with an embedded system for different motor faults was presented by Ayyappan et al 7 A power electronic converter‐based IM power hardware‐in‐the‐loop (PHIL) emulator for SITF detection was developed by Liu et al 32 However, these methods do not address the practical challenges of voltage imbalances and winding asymmetries. As stated by Shariatmadar 8 and Joksimovic and Penman, 9 the existing current spectrum analysis of chaotic systems is incapable of locating inter‐turn faults and cannot be used as a reliable indicator of the existence of SITF.…”

Monitoring the condition of induction motors requires continuous inspection of all motor components. The three-phase stator windings forming the critical components of the motors and handling heavy currents as high as twice the blocked rotor current under inter-turn short circuits necessitate a fault detection system that is efficient, appropriate, and worthwhile. The proposed algorithm takes measurements of the three-phase supply voltages and phase currents and plots their loci for each cycle under various fault levels. The proposed simple, nonintrusive, less expensive, and fault-sensitive voltage-current loci (£(v-i))-based technique accurately identifies the faulty phase and detects stator inter-turn faults (SITFs). In addition, the algorithm corrects supply voltage imbalances, winding asymmetries, and calibration errors of sensing elements. It contributes to examining the insulation condition of the stator windings at the onset and identifying the faulty phase of a motor. The experimental results for a 1 hp, 415 V squirrel-cage induction motor (SCIM) in a laboratory investigation validate the competence of the proposed technique under various fault levels and load conditions.

“…Emulators are widely used in industry [30], [31], [32], [33] and the proposed architecture can contribute to the realization of a complete emulator for an energy production turbine. In a possible practical scenario, the proposed DRC circuit is sided by circuits for the emulation of the other sensors and actuators present onboard the generators.…”

Some industries are in need of emulating banks with tens or hundreds of resistance temperature detectors (RTDs). This happens, for example, in the realization of the control electronics for big power generators employed in energy production. Unfortunately, the few RTD emulators commercially available are quite expensive, limited to few channels, and often do not present a true ohmic behavior. This work proposes a low-cost 10-b RTD emulator suitable for multichannel implementation. The proposed RTD is based on a nonstandard combination of "serial" and "parallel" resistive cells that allows the minimization of the effects of inaccuracies and parasitic elements and offers a true ohmic emulation. Mathematical models, simulations, and measurements on prototypes show that the proposed circuit emulates a temperature range between −100 and +450 °C, and it is monotonic and compliant to tolerance class "B" and/or "A" of the IEC 60751 standard.
