A predictive EMC method for inductive coupling, using measurements carried out on a sphere encompassing a tested device, is at the moment under development in our laboratory. This method makes it possible to construct an equivalent source in the form of a sum of multipole terms. Once the equivalent sources of two devices have been […]

This paper presents the use of a GTEM in an interlaboratory comparison. The GTEM cell is Gigahertz Transverse Electromagnetic waveguide, which has its operation described in IEC 61000-4-20. The comparison program of radiated emission was lead in accordance with CISPR 22, standard that normalizes limits and methods of measurement of radio disturbance for information technology […]

The objective of this study is to analyze the electromagnetic environment of the downtown area of Rio de Janeiro’s capital, before the Light Rail Vehicle (LRV) was routed. Electromagnetic field levels were measured and verified against proposed limits, concerning electromagnetic immunity of LRV. The results show that all measured places through the tramways do not […]
