... then used in the distance determination formula. The tests were made in a 3 meters semi-anechoic chamber- in order the results not to be affected by other radio frequency emissions from the surrounding environment- using a 20 Hz- 26.5 GHz EMI Test Receiver, a log-periodic antenna and RF Figure 1. Experimental test setup for ...

... simulation results, faults can be detected and signal. Wavelet technique analyzes signals in time and identified as soon as fault appears. In summary, if the system frequency domains and gets the results to describe the has a fault diagnosis structure, system dangerous situations can be avoided. character of the signals. The paper is ...

... both purposes. A problem can be identified when using corresponding data must be computed under 10 µs for a metallic coils because the temperature sensors required are 100kHz switching frequency. This is why the resistance reference is computed on a PC in order to minimize the 1 unnecessary processing load. This work was supported by a grant ...

... db8) to models is summarized in the range of 4.1ms to 7.91ms detect voltage sag/swell with and without positive/negative under different conditions. The sampling frequency was phase jumps. The performance of this method with respect 6.66kHz. This technique was also used in a benchmark to accuracy and detection time is better than ...

... faults are also troublesome [14]. over conventional three-phase motors, including reduced There is a growing interest in the analysis of multiphase torque ripple amplitude with higher frequency, reduced motors during fault operation. For example, [11] analyzes phase currents at the same phase voltage, therefore reducing the change in machine losses ...
