Abstract

A transformer is an electrical device that can increase or decrease voltage without changing the frequency of an alternating current (AC) supply. It is widely used in power networks to step up voltage for long-distance transmission and to step down voltage for distribution to consumers. Transformers are typically categorized into five types: power transformers, instrument (measurement) transformers, special-purpose transformers, autotransformers, and welding transformers. Power transformers can be oil-filled or dry-type; dry-type transformers are commonly installed indoors in large buildings and densely populated areas, whereas oil-filled transformers are used for temporary outdoor power supply needs.
