Time domain methods for the analysis of conducted interference on the power supply network of complex installations

Abstract

Conducted spurious phenomena cause interference in the power supply network of complex installations. The time dependent behaviour of these phenomena calls for dedicated measurement techniques in time domain. Quantities to measure are defined for DM as well as CM. Various measurement sensors are designed, implemented, characterised and tested. Frequency domain measurement equipment is not suitable for these time variant disturbances. Signal processing on the time domain data provides the necessary characteristics of the system. The proposed measurement methods provide a basis for the analysis of conducted behaviour of equipment as well as fixed installations.
