Abstract

Sistema para supervisar corrientes de fase y vibraciones de torsión de un turbogenerador trifásico, caracterizado porque incluye: una red de corriente de fase que funciona para producir tres señales de corriente de fase en respuesta a las tres corrientes de línea de dicho turbogenerador y para determinar una señal de corriente compuesta procedente de armónicas preelegidas de dichas señales de corriente de fase; una pluralidad de sondas situadas en un punto adyacente a un eje de dicho turbogenerador par detectar la velocidad de rotación de dicho eje y proporcionar una pluralidad de señales eléctricas; una red de vibraciones de torsión que puede funcionar para combinar dichas señales eléctricas con el fin de producir una primera señal de vibración conteniendo solamente componentes verdaderos de las vibraciones de torsión de dicho eje; un sistema de alarma adaptado para comparar dicha señal de corriente compuesta con un primer nivel de referencia y para comparar dicha segunda señal de vibración con un segundo nivel de referencia; y un registrador que puede funcionar en respuesta a dicha señal de alarma para registrar dicha primera señal de vibración y dichas señales de corriente en fase.
