Abstract

MÉTODO E DISPOSITIVO PARA MEDIR A IMPEDÂNCIA DE UM SISTEMA DE ATERRAMENTO. Trata-se de um procedimento para medir a impedância de um sistema de aterramento que compreende um circuito, sendo que o procedimento compreende, para cada frequência fi de um conjunto de frequências, F de uma varredura de frequência aplicada ao circuito do sistema de aterramento, gerar um sinal de modulação Ssinal (2) com uma frequência fixa fm, gerar um sinal de portadora Sportadora (1) com a frequência fi, e obter um sinal modulado em amplitude Smodulado (3) com componentes de frequência das frequências fm e fi e com base em Ssinal (2) e Sportadora (1).
