Electromagnetic phenomena in impulse voltage measuring systems

This paper deals with the theoretical and experimental studies of induced voltages in high voltage test circuits. These induced voltages are produced by electromagnetic radiation fields arising from travel - ling waves (current and charge) along the lead in the measuring system. These travelling waves are known to exist. The radiation fields can be calculated by applying distribution theory to the wave equations. All the relevant phenomena are presented and discussed for a measuring system in an indoor U.H.V. Laboratory. This contribution gives some explanation to questions of measurement phenomena and represents the first fundamental study of this topic.
