Course content

Design of installations and equipment requires both a physical understanding and knowledge of mathematical modelling. Further there is a need to use analytical and numerical methodes to solve sets of equations. In this course several practical problems connected to installations and devices will be highlighted. The students use basic field- and circuit theory to determine parameters which characterise the installation or the different components. Adressed topics are: Circuit models for magnetic, thermal and electrical problems; analogies. Use of dielectric insulation material, field control, shielding. Conductor and contact problems, overheating, bus dimensioning. Magnetic fields, magnetic materials, dynamic magnetic coupled circuits, windings. Eddy currents - surface power density, proximity effects. Inductance, resistance and capacitance. Circuit models. Grounding models. Line/Cabel models. Forces. Energy consideration. Simple modeles for electrical machines.
