Desenvolvimento de antenas para aplicação na detecção de impulsos de corrente injetados em malhas de aterramento.

Abstract

In this work, antennas for low frequencies are presented, in the order of mega-hertz, which can be applied in the acquisition of electromagnetic signals emitted by ground loops submitted to current impulses. The use of antennas appears as a new technique for analyzing the response of the grounding loop, being a non-invasive monitoring method, with low cost of manufacture and can be applied to detect signals that have high frequencies.
