Abstract

La invención proporciona un ensamble de sensor para determinar la concentración de hidrógeno en un fluido aislante en equipos de generación, transmisión y distribución de energía eléctrica. El ensamble incluye un alojamiento que tiene una abertura en la misma comunicación con el fluido, un sensor de hidrógeno dispuesto en el alojamiento y sensible a la concentración de hidrógeno en el líquido y la generación de una señal relacionada con la concentración de hidrógeno y un sensor de presión dispuesto en el alojamiento sensible al fluido y generar una segunda señal indicativa de la presión del fluido en el equipo. El ensamble incluye además un procesador de señal dispuesto en el alojamiento y conectado al sensor de hidrógeno y el sensor de presión y sensible a las primera y segunda señales para generar una tercera señal que representa la concentración de hidrógeno en el fluido.
