Recent work completed by CIGRE/CIRED Joint Working Groups C4.108 and C4.111 has pointed to the general conclusion that there is a poor correlation between measured voltage fluctuation levels (“flicker”) and complaints from network customers. Voltage fluctuation measurement procedures have long been standardized in the IEC flickermeter (IEC Standard 61000-4-15) and historically the correlation between...
The early failure detection of induction motors is considered very important in order to ensure their stability and high performance. Thus, condition monitoring of these motors are essential to ensure that. However, the effectiveness of the fault diagnosis depends on the quality of the fault features selection that is used in the adopted method. In this way, this paper will present a comparative study...
Electric arc welding and cutting processes require delivery of the electrical power covering the broad range of the output voltage and the output current. Direct approach in the design to cover all required range leads to oversizing of the applied elements of the power conversion. The solution of the coverage the high voltage in the low current range, needed for the welding by means of the electrodes...
