Description of the lecture

The lecture deals with the background of different systems to test high voltage components. The generation of high voltages and currents under laboratory conditions as well as different measurement techniques for high voltages and currents are introduced. Furthermore, various reasons for the occurrence of measurement uncertainties are presented and countermeasures against uncertainties are derived. The gained knowledge is deepened by means of various test circuits.
