Introduction: Medium voltage reclosers are representing nowadays an important link between transmission power systems and low voltage grids. With a high level of renewable energy penetration, the medium voltage networks are becoming bidirectional. Therefore, the associated switching ... En savoir plus

Due to the increase on the academic and industrial interest on thermal energy storage (TES) systems, the EU Horizon project HYSTORE is developing 4 different solutions. In these solutions, the use of thermochemical materials (TCM) and phase-change materials (PCM) are proposed. We ... En savoir plus

Induction motors, as any other industrial products, have to comply with various requirements on noise levels. Therefore, it is essential to use an appropriate prediction tool to verify and optimize the design of an induction motor with respect to the acoustic performances. The paper ... En savoir plus

Binary meta-optical structures offer many new possibilities in the efficient manufacturing of products like diffractive beam splitters, phase correction elements, gratings and many more. At JENOPTIK we manufacture a variety of optical elements, based on electron beam lithography (EBL) ... En savoir plus

Vacuum distillation furnaces (VDFs) are employed for purification and consolidation of heavy metals from their dendritic forms which are entrained with molten salts. The VDF is an induction heated furnace which is operated at a temperature of 700-1400 °C and at a pressure of 0.01-600 ... En savoir plus

Electromagnetic force and density in the electric-machinery dynamic system are fundamental forces which cause physical phenomena such as structural deformation, vibration, noise etc. But when two materials are contacted, electromagnetic contact force and distribution by conventional ...

The AC losses that superconducting magnet systems experience during transient events are an important design consideration in fusion reactors. We present results on the approach for calculating AC losses in the high temperature superconducting (HTS) toroidal field (TF) magnets of the ... En savoir plus

Field-emitter (FE) electron sources offer significant advantages over photocathode and thermionic sources due to their ability to be operated without the need for an auxiliary laser system or a heating source. While FE cathodes have been traditionally used in DC environments, we explore ... En savoir plus
