  • SF6: No Leak Too Small | TD World

    The Trafag gas monitors do not have any control function on the breakers to isolate sections of the GIS; instead, they only supply both a low and low-low alarm indication. The theoretical design limit of the GIS bus and breakers is that at zero SF 6 pressure, the components' insulation systems will withstand 1.0 per unit line-to-ground voltage. Throughout the design process, this fail-safe philosophy was employed when practical.

  • How does GIS for Water Leak Detection Work? - The Water

    Moreover, the dielectric constant (relative permittivity) of pure water makes it easy to detect a leak. With the increase of the dielectric constant, the electric flux density will increase. (Remember that microwaves are electromagnetic waves!) Water has a high dielectric permittivity, which enables the detection and measurement of water in soil.
