Abstract

Un aparato y método de análisis inteligente para equipos eléctricos llenos con fluido incluye sensores para medir diversos parámetros de los equipos eléctricos. El modelo analítico calcula parámetros en base a mediciones de otros parámetros. Los parámetros medidos y calculados son comparados y el resultado de la comparacion se utiliza como un indicador en una red causal. Las probabilidades de la red causal son recalculadas por una red de confirmacion. Los modelos analíticos son ajustados durante el tiempo para tener en cuenta cambios aceptables en el funcionamiento de los equipos eléctricos durante el tiempo. La salida de la red causal puede ser utilizada para indicacion de diagnostico y pronostico.
