Abstract

DETECçãO DE FALHA DE ALTA IMPEDáNCIA Um aparelho, sistema e método para detectar falhas de alta impedância em linhas de energia elétrica utilizando um sistema de detecção de falha de alta impedância composto possuindo uma lógica de saída que amostra as saídas lógicas de uma pluralidade de sistemas de detecção de alta impedância independentes e determina uma falha de alta impedância se quaisquer dois dentre a pluralidade de sistemas de detecção de alta impedância independentes indicarem uma falha de alta impedância. Preferivelmente, a pluralidade de sistemas de detecção de alta impedância inclui um sistema de detecção de falha de alta impedância com base em wavelet, possuindo uma primeira saída lógica, um sistema de detecção de falha de alta impedância com base em estatísticas de ordem superior possuindo uma segunda saída lógica, e um sistema de detecção de falha de alta impedância com base em rede neural possuindo uma terceira saída lógica. Preferivelmente, cada um dentre a pluralidade de sistemas de detecção de falha de alta impedância inclui um aplicativo de detecção de falha de alta impedância independente que detecta de forma independente uma falha de alta impedância na linha de energia elétrica.
