Estudo do ambiente eletromagnético em subestação de alta tensão e a importância do aterramento da blindagem dos cabos de controle.

Abstract

This work aims at study the effects to which the control cables installed in high voltage substations are subject, as well as portray the grounding of the shield of these cables so that its function in the best way possible. The work consists of a theoretical study on the aspects that involve the kinds of phenomena to which the control cables installed in substations are exposed, characterizing the relevance of the problem, the electromagnetic environment in high voltage substations, the coupling mechanisms of electromagnetic fields portraying the problem mitigation techniques.
