In this paper, an analytical model for evaluating the shielding effectiveness of rectangular enclosures with a perforated wall was proposed. Apertures in the perforation can be performed in a staggered pattern, while the perforation can be situated at an arbitrary position on the enclosure wall irradiated by an electromagnetic field. The results of the SE calculations using the proposed model and finite element method are presented. They are in good agreement in the frequency range up to 1 GHz. The shielding effectiveness of the ABB FOX515 multiplexer enclosure used in the electric power complex was also evaluated.
