Considerations about the measurement of electromagnetic emissions

Abstract

he main goal of the paper is to present procedures and analysis of the measurement that must be performed and the compulsory results to obtain compliance with conducted and radiated electromagnetic emissions. After the introductory section which outlines generalities related to electromagnetic compatibility (EMC), the second section focuses on the dichotomy between near-field and far-field, present in two important zones where electromagnetic phenomena are totally different, which however are not well enough highlighted in the specific EMC standards. The third section is devoted to emission measurements that must be performed in different electromagnetic environments and for different types of equipment depicted in the specific standards in force. As an example, the case of electromagnetic emissions produced by a household gas thermal power unit is presented.
