Gas insulated power transformers: A growing technology - EE

Mar 12, 2018 · Gas insulated transformers (GITs) have been in use since the 1960s, but use has been restricted due to higher costs and other reasons. Gas is used as an insulating and cooling agent in gas insulated transformers. Sulphur hexafluoride (SF 6) is the main gas used in these types of transformer at present although other gases are under development. The main advantage of gas insulated transformers is that they are environmentally friendly and can be recycled easily.Get price

Dissolved gas data in transformer oil---Fault Diagnosis of

Jan 14, 2019 · Abstract. The oil-paper insulation system in power transformers operates under the effects of high temperature and strong electromagnetic environment, and the insulation medium can slowly decompose into a number of small molecules. The decomposition gases dissolved in oil are H2, CH4, C2H6, C2H4, C2H2. When a fault occurs, the insulation breaks down more quickly and the decomposition products will be different according to the type and severity of the fault.Get price

Transformer Isolation - Technical Articles

IntroductionWhy Isolation?Isolation Transformer ConstructionSpecial Purpose Isolation TransformersSafety AlwaysElectrical isolation is necessary to protect circuits, equipment, and people from shocks and short circuits as well as to make accurate measurements. Isolation, also referred to as galvanic isolation, means no direct conduction path exists for the current to flow; no physical connection exists. Isolation can be accomplished using electromagnetic, capacitive, or optical devices. While physically and electrically isolating the circuitry from unwanted currents, required signals and power need to be transferred across the separated circuits. To transfer signals, transformers use magnetic flux, capacitive isolators use differential voltage and optocouplers use light to bridge the gap. This article discusses the use of isolation transformers.Get price
