What is a Transformer Connection?Three-phase Transformer Connections DefinitionA three-phase transformer connects its primary and secondary windings in star or delta configurations for various electrical applications.Star ConnectionIn star connection, three windings connect at one end to form a neutral point, used for creating a neutral terminal.In star connection, a line-to-line current is the same as a line-to-neutral current.we can find that the line-to-line voltage is √3 times line-to-neutra
