NDIR SF6-Air testing for gis

NDIR SF6-Air testing for gis

6 insulated test transformers are especially designed for testing metal-clad switchgear (GIS) in the factory and on-site, and for testing on-site substation equipment. The conventional transformers can be flanged directly to the GIS. This makes testing of such GIS installations possible without feeding them through an air-SF 6 bushing ...

  • 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.
