  • Hydrogen sensor, hydrogen detection system employing the same, and electrical device with a hydrogen detection system
    Patent number: 10488388
    Abstract: An optical sensor for detecting hydrogen in a fluid in physical contact with the sensor is provided. The sensor includes an optical fiber, wherein an end portion of the optical fiber is coated with a multilayer including: a sensing layer, including a film of an alloy, the alloy including Mg, Ni, and M, wherein M is at least one of Zr, Ta, and Hf, and wherein the alloy has the composition MgxNiyMz, and wherein x is from 40 to 60, y is from 10 to 40, and z is from 10 to 40, and a catalyst layer including Pd. Further, a detection system for hydrogen, including such an optical sensor, and an electrical device having such a detection system are provided.

  • Sensor assembly and method for sensing status condition of electrical equipment
    Patent number: 9377451
    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.
