[0002] A transformer is an electrical device whose main function is to change AC voltage. That is, voltage conversion, power transmission, load matching, electrical isolation, filtering, and multi-winding applications. The working principle of the transformer is based on the law of electromagnetic induction. When current passes through one winding (primary winding), an induced voltage is generated in another winding (secondary winding). The voltage ratio depends on the turns ratio of the two windings.

[0003] There are many types of transformers, which are mainly classified according to their application, structure and function. Some common types of transformers are: oil-immersed transformers, dry-type transformers, power transformers, distribution transformers, control transformers, isolation transformers, autotransformers, voltage regulating transformers, audio transformers, pulse transformers and special transformers: including current transformers, voltage transformers, furnace transformers, mining transformers, etc.
