Moreover, the material damping varies largely with respect to frequency and the actual approaches for its estimation are limited within restricted frequency ranges. An approach for estimating the material damping within the overall frequency range does not exist in the literature. This paper proposes ...
A motor drive system includes a step down phase shifting isolation transformer structured to receive medium voltage AC power from an AC bus and convert the medium voltage AC power t
The main difficulties facing the operation of parallel converters in DC microgrids (DCMGs) are load sharing, circulation current, and bus voltage regulation. A droop controller is commonly used to control current sharing among parallel DC–DC converters due to its simplicity. However, the values of...
Although the abovementioned studies have covered a wide range of issues and solutions for DSSE, it is worth noting that all these studies are focused on medium-voltage (MV) distribution grids, i.e., voltage levels higher than 0.4 kV. Low-voltage (LV) distribution grids, i.e., 0.4 kV,...
that the strain rate substantially affects the stress–strain relationship of PC/ABS. At lower strain-rate ranges, the necking deformation can be ignored, but not at higher strain rates [8]. Reis et al. examined the impact of temperature and strain rate on the tensile behavior of high-densit...
Ekip Up is the low voltage digital unit for next generation of plans Service Full range of Products and Services for entire equipment lifecycle Experience Center Enhance customer experience with ABB solutions NEMA Circuit Breakers Ranges from Power Break II/HPC (up to 4000 amps) to TEY/TED (down...
In comparison with other studies in the literature, the algorithm accuracy for identifying a faulty branch, was found to be superior to a conventional method for the LV grid but also better than two methods from the medium voltage case. A great feature of the algorithm was that, as can be...
Figure 4g, h demonstrate a CNT TFT-based voltage tunable-gain amplifier. In addition to fast and medium-complexity digital circuits, we also show the potentials of using CNT TFT for high-gain compact-sized amplifiers. We first developed an accurate CNT TFT device model, which was used for si...
