Abstract: A sensor assembly is disclosed for sensing a status condition of a liquid-filled electrical equipment such as a transformer. The sensor assembly can include a light source; a first hydrogen detection section, the first hydrogen detection section being optically coupled to the light source for receiving light from the light source, wherein the first hydrogen detection section has a first hydrogen sensitive layer that changes an optical response with respect to the received light depending on whether an amount of hydrogen at the first hydrogen sensitive layer is above or below a first threshold; and a first output section optically coupled to the first hydrogen detection section for receiving light having interacted with the first hydrogen sensitive layer such that the received light depends on the optical response of the first hydrogen sensitive layer.

Abstract: A sensor assembly senses hydrogen and moisture content of insulation liquid of a liquid-filled electrical equipment. The sensor assembly includes a radiation source for emitting electromagnetic radiation, a water detection section for receiving a water-containing component of the liquid when the assembly is in operational connection with the electrical equipment and for being illuminated by electromagnetic radiation from the radiation source, a first detector for detecting electromagnetic radiation from the water detection section at a wavelength indicative of an amount of water present at the water detection section, a hydrogen detection section for receiving a hydrogen-containing component of the liquid when the assembly is in operational connection with the electrical equipment and for being illuminated by electromagnetic radiation from the radiation source, and a second detector for detecting electromagnetic radiation from the hydrogen detection section at a wavelength indicative of an amount of hydrogen present at the hydrogen detection section.
