For its different video alarm levels, it is the best tool to reduce environmental pollution and SF6 gas leakage.

Electrical Transformer End-of-Life Hazardous Waste Removal use massive step-up transformers to increase voltage (aka tension) in order to push electricity more efficiently through long-distance transmission lines—hence the term "high tension wires." They use step-down transformers, for example, to reduce voltage to the relatively safe and familiar 120/220 VAC we have in our homes.

Valves Archives - AVT Services has been used extensively in high voltage circuit breakers and other switch gear employed by the power industry. Applications for SF6 include gas insulated transmission lines and gas insulated power distribution substations. The combined electrical, physical, chemical and thermal properties offer many advantages when used in power switch gear.

Installation guidelines for MV metal-enclosed switchgear ...· IEC 62271-200 covers both switchgear in which atmospheric air acts as the gaseous insulation within the enclosures and also switchgear in which an insulating medium in the form of a fluid other than the atmospheric air (e.g. SF6) is used. So, we have an air-insulated switchgear (AIS) and gas-insulated switchgear (GIS). Interesting reading:

sf6 gas recovery system in brazil - schallmarkus.de (Sulfur Hexafluoride) Recovery | Hudson Technologies is widely used as an insulating and arc quenching gas in medium and high voltage transformers. As equipment ages, it is being repaired or replaced with more efficient equipment which typically uses 1/3 the quantity of SF6. This creates a need to recover the SF6 for recycling or disposal.Missing: brazil92%

High voltage | Air Liquide Electronics Systems help this industry reduce its greenhouse gas emissions, the market's main players have developed alternative insulating gas mixtures, and Air Liquide accompanies them with their distribution. These eco-friendly mixtures and the equipment required to handle them are defining the future of the gas insulated substations (GIS) and gas insulated lines (GIL) market worldwide.

TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING … gas insulated substation (GIS) uses a superior dielectric gas, SF6, at moderate pressure for phase to phase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in SF6 gas inside grounded metal enclosures.

Insulation components and materials - Hitachi ABB Power Grids lifetime of a transformer depends on the reliability of the insulation used. Hitachi ABB Power Grids pays particular attention to the manufacturing systems and processes used and continues to improve product quality and reliability by investing in modern equipment and experienced people.

g3 Technology - GE Grid Solutions - PDF Catalogs ... hexafluoride (SFe), an insulating gas used in high-voltage switchgear, is estimated to contribute 23,500 times more than carbon dioxide (CO2) to the greenhouse effect and can remain in the atmosphere for 3,200 years. Previously, Power Generation and Transmission utilities had no alternative to SFe for these products.

Siemens to provide UK's first SF6 free 145kV vacuum ... uses a gas mix similar to the air we breathe, made up of nitrogen (80%) and oxygen (20%), as a carbon free alternative to SF6 which has traditionally been the method of insulation in high voltage switchgear since the 1960s. The chemical properties of SF6 gas make it ideal for electrical insulation and arc quenching in high-voltage switchgear.

Gas Insulated Switchgear | Products & Suppliers ...: The RH Systems Model 973-SF6 Analyzer was specifically designed for measurement of humidity and SF6 purity in gas insulated switchgear systems. Humidity measurement data is displayed in ppmv, ppmw and dew/frost point at either system pressure or standard pressure.
