In this paper we present a technological problem encountered in the machining accuracy of the parts for aerospace, made of aluminum alloy extruded profile with 7 meters length. Those parts have very tight tolerances and on milling process appears deviation due to thermal expansion effect, which influences the repeatability of machining processes. T...

The DSWIG scheme proposed in this paper uses an inverter with apparent power lower than the corresponding generator power. The expected ratio between the inverter power and the generator power is 50% in the case of DSWIG. This is similar to DFIG applications. The advantage of DSWIG is the lack of brushes. DSWIG can be used in variable speed applica...

The paper achieves a study on the reactive power consumption in case of a medium sized factory. The factories as others industrial consumers usually have the power factor lower than the neutral one, which in Romania is 0.92; that is why these types of consumers have to pay for reactive power. The reason for the power factor is small (sometimes much...
