An important use of electric transformers is moving electricity from energy plants to properties and businesses. Electric transformers is often of high voltage with the power plant. Voltage is little lowered when it reaches the substation. It can transform alternating current from one circuit into another via electromagnetic induction. This generally involves ferromagnetic core and some coils called windings. It may either be a single-phase or maybe a three-phase configuration. There are various kinds of electrical transformers just like site, Portable, Low voltage, Enclosed, Screen Mounted, Three phase, Evaluation Lamp units along with custom Electrical transformers.
