Proper grounding of RF-shielded rooms
When Michael Faraday invented his ‘Faraday Cage’ at the end of the 19th century, he could never have imagined how important his invention would become in today’s electrical engineering world. This is very important because for EMC measuring rooms, MRI and TEMPEST/EMP applications, his invention is still indispensable for protecting equipment from outside radiation effects. But not only that. The ‘Faraday cage’ also prevents important data used at data centres or military installations from being captured through surveillance and eavesdropping. Connecting the RF-shielded room to a high-quality ground is necessary for optimal functionality in almost all applications. We asked expert Jan Kappert, to explain why it is essential and how to prepare it.
