The Benefits of Applying
IEC 61000-5-2 to Cable Shield Bonding and Earthing

(Word format, 406K)

Traditional practice is to bond cable shields (screens) to the earth (ground) at one end only, using a length or wire. This brief article shows why this is very bad for EMC, and explains how the IEC 61000-5-2 mesh-bonding approach works so well. Other links and downloads on this page explain how it is that this approach, which bonds cable sheilds at both ends, actually benefits pro-audio quality and saves installation and commissioning time – if the electronics are designed correctly.
