Abstract

no campo da proteção do transformador de energia, foi fornecido um método para proteger um transformador de energia que compreende as etapas de: (a) monitoração de um sinal externo de indicação de falha (12a, 12b, 12c); (b) execução local de uma determinação de falha; (c) execução local de uma determinação de corrente de irrupção; e (d) emitir a sinal de disparo final (48) para proteger o transformador de energia caso: (i) o sinal externo de indicação de falha (12a, 12b, 12c) identifica que uma falha ocorreu e a determinação de falha localmente executada confirma que uma falha ocorreu; ou (ii) o sinal externo de indicação de falha (12a, 12b, 12c) identifica que uma falha ocorreu e a determinação de falha localmente executada identifica que nenhuma falha ocorreu, entretanto, após um atraso predeterminado, a determinação de corrente de irrupção executada localmente confirma a ausência de uma corrente de irrupção.
