Substation and switchgear techs: GIS is seen everywhere ...· The battle between insulated substation technologies is not new, says Ahmed Mousa, Manager: Distribution & 69kV Transmission Planning at PSEG, US but the differences between Air Insulated Switchgear (AIS) and Gas Insulated Switchgear (GIS) as well as the elements that make gas more attractive than air, remains a topic of interest.
Switchgear - Wikipedia for lower voltages may be entirely enclosed within a building. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air, although this requires a large amount of space. Gas-insulated switchgear saves space compared with air-insulated equipment, although the equipment cost is higher.

The history of gas-insulated substations | Think Grid 6 gas was already known during the 1940s. Westinghouse holds the original patent for the use of SF 6 as interrupting medium, and their engineers developed the first applications for switches and circuit breakers in the early 1950s. In the 1960s all major manufacturers such as BBC-Calor Emag, Siemens, Magrini, Merlin-Gerin, NEI-Reyrolle, the Japanese and Delle-Alsthom had started intensive ...
Science Behind the BioCharger - BioCharger, the limitation of this design is that the vacuum tubes would not pulse at the higher Rife [Raymond Royal Rife frequencies and were limited to approx 1,000 hertz, far less than the 50,000 hertz [50 kilo-hertz] Rife utilized. Another drawback was that this model was very cumbersome, weighing …
