    7. Objectives, learning outcomes and obtained knowledge

    The main aim of the subject is to introduce the latest techniques of calculation and measurement of high voltage and high current, which is the basis of the economic and safe operation of many electrical equipment. This is the theoretical and practical principle of the reliable operation of grids – with a voltage level of a few hundred kilovolts and nominal (or fault) current of a few kiloamper – the insulators, or the connectors and mounting units.
