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.

Course contents

  • Dimensioning of test systems to generate high AC, DC or impulse voltages
  • Test systems to generate high currents
  • Measurement of electrical parameters in high voltage applications as well as under laboratory conditions
  • Measurement dividers: Working principle and specific advantages and disadvantages
  • Fundamentals of partial discharge measurement and diagnostics
