Abstract

"MéTODO E REDE PARA TOLERAR UMA FALHA EM CONCENTRADORES E LINHAS". Concentradores 11-14 são conectados de forma circular entre si. Os concentradores 11 e 12 são supridos com energia elétrica pela fonte de energia 1 e os concentradores 13 e 14 são supridos com energia elétrica pela fonte de energia 2. Cada um dos terminais 7-10 possui duas portas, cada uma das quais é conectada ao concentrador suprido de uma fonte de energia diferente.
