Chapter 2 Grounding & Shielding - TU Delft

47 Chapter 2 Grounding & ShieldingSafety, system protection and performance are the three main reasons to earth asystem. Not all electronic equipment needs to be connected to earth to work,satellites are an example. Sometimes wrong Grounding configurations, oriented tosatisfy the special power and performance requirements of electronic loadingequipment, can compromise safety rules generating dangerous situations forpersonnel and equipment. Personnel safety, equipment safety and performancegrounding issues have to be analyzed together. In any case, safety rules must not beviolated. All these concepts as well as the relations between ground issues need tobe clarified before passing on to a higher level in the control of the electromagneticemissions of the system. Along the present Chapter , concepts like safety Grounding ,signal or ground reference plane as well as Grounding topologies to achieve electricsafety and good performance of the system, are presented.

grounding electrode system, proper system grounding of service equipment and separately derived sources and proper equipment grounding for operational frequencies (DC or AC-mains) as well as higher frequencies. It is recommended that the grounding design and installation be compliant to all applicable codes and standards [4][5].
