  • Decomposition Characteristics of SF6 and Partial Discharge

    The decomposition characteristics of SF6 under four types of negative DC partial discharge (DC-PD) are obtained. The relationship between the decomposition characteristics of SF6 and the PD types was further studied. Moreover, back propagation (BP) neural network algorithm [29–38] is used to recognize the PD types.

  • Nondispersive infrared sensor - Wikipedia

    A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.
