Integrating seamlessly with the sf 6 Leak Detector. This multipoint sampler extends its area monitoring capability. It enables a good spatial resolution in the leak detec-tion with a good flexibility in the choice of the sampling locations. Field Monitoring Ease of use, and long-term stability are required for the mostly unmanned GIS substations. With its low detection limit (6 ppb), and its accuracy over a high dynamic range, the permanent monitoring solution from LumaSense enables early leak detection in comparison with monthly visual checks of density gauges. The insulating gas Leak Detector can complimentarily meet the health & safety requirements in enclosed areas where insulating gas leaks may occur. Sampling points can indeed be located in low lying and confined areas where gaz sf6 would build up over its MAC level (1000 ppm) or even up to an asphyxia-tion risk level. Alarm relays can be set up on two...Get price

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.Get price

Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, gaz sf6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in sf 6 gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what Sulfr hexafluoride can do in centimeters.Get price
