Abstract

MéTODO PARA DETECçãO E LOCALIZAçãO DE UMA FALHA NO ATERRAMENTO ELéTRICO EM UMA LINHA ELéTRICA. Trata-se de um método para detecção e localização de uma falha no aterramento elétrico em uma linha elétrica, do tipo que compreende várias cargas elétricas conectadas a uma linha elétrica (L) e alimentado por um aparelho de alimentação e controle (1), cada carga elétrica consistindo de um elemento de carga e um dispositivo auxiliar, conectados eletricamente um ao outro, o referido método compreendendo: transmitir, pela linha elétrica (L), ao menos um primeiro sinal de controle ((S(i+l))) de um primeiro dispositivo auxiliar (D1), associado a uma primeira carga correspondente (Ci) que pertence ao grupo de várias cargas elétricas, para um segundo dispositivo auxiliar ((Di+1)), associado a uma segunda carga correspondente ((Ci+1)), adjacente à primeira carga (C1), que pertence ao grupo de várias cargas elétricas; receber, pelo segundo dispositivo auxiliar ((Di+1)), o primeiro sinal de controle ((S(i,i+1))) transmitido pelo primeiro dispositivo auxiliar (Di); e transmitir, pelo segundo dispositivo auxiliar ((Di-f- 1)), um primeiro sinal de informação (Inf(i+1 ,i)) para o aparelho de alimentação e controle (1).
