Electromagnetic shielding and earthing

Abstract

The article discusses the issue of electromagnetic shielding of electrical devices, equipment or systems for protection against electromagnetic (EM) interference. EM shielding is a process of limiting the coupling between the source of interference and the victim. The effectiveness of shielding depends on the material parameters and geometry of the shielding, the frequency of the incident field and whether the source of EM interference is close or far away. The basic measures for solving EMC problems also include grounding and equipotentialization. When conducting LF currents and impulse currents, the same grounding conductor behaves completely differently. The main purpose of equipotentialization is to protect living beings and electronic circuits that are very sensitive to possible potential differences.
