Abstract

Patente de Invenção: <B>"SISTEMA E MéTODO DE ANáLISE INTELIGENTE DE EQUIPAMENTO ELéTRICO CHEIO DE FLUIDO"<D>. Um aparelho de análise inteligente (10) e método para equipamento elétrico cheio de fluido (F) (20) inclui sensores (28a~e) para medir vários parâmetros do equipamento elétrico (20). Modelo analítico (112, 114, 116) calcula parâmetros baseado em medidas de outros parâmetros. Os parâmetros medidos e calculados são comparados e o resultado da comparação é usado como um indicador em uma rede causal. As probabilidades da rede causal são recalculadas por uma rede de julgamento. Os modelos analíticos (112, 114, 116) são ajustados com o passar do tempo para computar mudanças aceitáveis no comportamento do equipamento com o passar do tempo. A saída da rede causal pode ser usada para diagnóstico e indicação de prognóstico.
