Learning outcome - Objectives
Knowledge: By the end of the course the students will be able: to understand basic concepts and phenomena relevant to dimensioning and evaluation of high voltage (HV) components with regard to electrical, electro-mechanical, and thermal stress of insulators and conductors, to identify key component’s parameters and define critical quantities/figures of HV components, to examine the influence of the identified component’s parameters on the critical quantities/figures, to differentiate and subsequently prioritise the critical figures with regard to safe and reliable operation of a particular component/insulator, as well as to reliably estimate values and uncertainties of relevant figures. Skills: By the completion of the course the students should be able: to identify electric field characteristics (as well other related quantities, e.g., temperature, pressure, current, etc.,) and material parameters appropriate for a particular HV problem, to use analytical methods to estimate: HV components/insulation characteristics, potential relief in the electric stress due to proper component dimensioning/grading, possible value of electric field build up due to insulation defects, to develop, modify and, use finite-difference numerical codes for computing and visualization of electric fields and voltage distributions, to set up and use electric schematic evaluators for steady-state and transient thermal analyses and ampacity evaluation of HV cables, to simulate electric stress using CST EM studio, to make a state of the art review on a particular HV problem using available databases (e.g., ieeexplore), as well as to evaluate reliability of the available formulas and approaches for HV problems. Competence: By the completion of the course, the students should have developed a basic vision of existing methods and tools relevant to design and analysis of HV components/insulators.   Completion of the course assignments requires the student (a) to elaborate the work plan for every assignment, (b) to list modelling approximations/assumptions, (c) to define the figures of interest, (d) to configure evaluation tools, (e) to interpret the evaluation results, (f) to present the completed assignment in the form of a report describing the problem formulation, description of methods, results, conclusion, and bibliography.
