Isolation transformer - Wikipedia

An isolation transformer is a transformer used to transfer electrical power from a source of alternating current power to some equipment or device while isolating the powered device from the power source, usually for safety reasons. Isolation transformers provide galvanic isolation; no conductive path is present between source and load. This isolation is used to protect against electric shock, to suppress electrical noise in sensitive devices, or to transfer power between two circuits which mustGet 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

Distribution Transformer : Construction, Types and Its Uses

Distribution Transformer ConstructionTypes of Distribution TransformerUses/ApplicationsFAQsThe designing of a distribution transformer can be done similarly to small size transformers. The main parts of this transformer mainly include Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing. 1. The oil tank is used to soak the windings by placing it in. 2. A conservator is arranged above the oil tank at the outside of the transformer frame. It is connected to the main tank with the help of a metallic tube. The oil within the tank can be easily contacted & enlarge throughout loading so that the temperature of the oil can be increased & decrease. 3. Buchholz relay is used when a conservator tank is used. Because it indicates errors like loss of oil once it goes low, improper flow of oil between the tank & transformer. 4. Breather Unit includes silica gel that absorbs moisture in the oil. It changes its color from blue color to pink color it is not capable to absorb moisture in the...Get price
