ABSTRACT: Sources of electromagnetic radiation, present everywhere in our civilization, can seriously affect the operation of susceptible equipment in nearby areas. Common solutions consist of increasing the immunity of equipment or shielding the spaces that contain them. However, there are many particular cases where such solutions are not applicable. A common example is that of electrical measurements, made with broadband instruments in areas that cannot be shielded for various reasons. For such situations, we have devised a method of reducing perturbative influences using partial shielding, grounding and rejection solutions. The method was applied to an experimental space exposed to a wide variety of strong perturbations, in a wide range of frequencies, which seriously affected the operation of oscilloscopes. The results highlighted the effectiveness of different applied solutions and allowed the problem to be solved.KEYWORDS: Electromagnetic compatibility, Electromagnetic perturbations, Electromagnetic Interference, Electromagnetic Susceptibility, Electromagnetic ShieldingRead full text (pdf)
