Acquis d'apprentissage (objectifs d'apprentissage) de l'unité d'enseignement
At the end of the course, students will be able to:
* demonstrate a knowledge and understanding of the main electrical properties of solid insulators and explain their dependence with applied voltage and frequency;
* understand how fundamental theories can be applied to the analysis of their physical properties;
* understand the fundamental mechanisms leading to dielectric breakdown and how they can be probed experimentally;
* understand the important concepts involved in static electricity;
* understand how extrinsic effects (electrodes, geometry, parasitic inductances and capacitances) can affect the results of electrical measurement on insulators;
* demonstrate practical skills as well as the ability to carry out successful measurements of low-level currents;
* show what are important electrical properties of insulators in high voltage engineering applications.
