Shielding Effectiveness of Cabinets using IEEE 299 and IEEE 299.1 and Effect of Loading

Abstract

One major electromagnetic compatibility technique is shielding. It is the basic technique to create a barrier between different electromagnetic zones. Shielding effectiveness measurement procedures are compared, and applied to a cabinet. Flaws in measurement procedures and some suggestions for improvements are discussed. Loading a cabinet with equipment and the effect on shielding effectiveness is shown.
