Measuring EMC of HV Cables & Components with the Triaxial Cell
Published in "Wire & Cable Technology International", Januar and March 2012
Authors: Dipl.-Ing. Bernhard Mund, bedea Berkenhoff & Drebes GmbH und Dipl.-Ing. Thomas Schmid, Rosenberger Hochfrequenztechnik
Content: This article describes the capabilities of the newly developed Triaxial Cell. The question of whether and whwn transfer impedance can be measured with or without matching is examined and a new test method "unmatch-match-short" for measuring the transfer impedance is presented.
