Autotransformer
An autotransformer refers to a transformer whose windings are primary and secondary on the same winding, with the primary and secondary windings directly connected in series and self coupled. According to the structure, it can be further divided into adjustable pressure and fixed type. Autocoupling means electromagnetic coupling. Ordinary transformers transmit energy through electromagnetic coupling between the primary and secondary coils, without direct electrical connection between the primary and secondary sides. Autocoupling transformers have direct electrical connection between the primary and secondary sides, and their low-voltage coils are part of the high-voltage coils. Autotransformers and other protective devices are also used in the protection equipment of communication lines.
