Electromagnetic disturbances from natural phenomena such as lightning, or
those generated from industrial activity, can cause harmful interference in
onboard electronic systems. The disturbances are generally transformed into
radiated and conducted disturbances, using wired connections to spread their
effects in electrical and electronic systems. In order to identify the paths
of propagation and coupling of these HF currents into a complete system and
propose solutions to reduce EMC interference, it is necessary and important
to carry out experimental case studies on the coupling between shielded as
well as unarmoured cables, in order to identify the importance of
differential and common-mode currents. Measurements were made using a 4-way
vector network analyser giving the results of the crosstalk between victim
and culprit cables as well as for module and phase.
