There are several types of transformers used in electrical engineering. Some common types include:
- Power transformers: These are used in power transmission and distribution systems to step up or step down voltages.
- Distribution transformers: These are used to step down the voltage for distribution to households and commercial buildings.
- Instrument transformers: These are used for measurement and protection purposes, such as current transformers (CTs) and voltage transformers (VTs).
- Autotransformers: These have a single winding that serves as both the primary and secondary winding, resulting in a voltage transformation ratio between the input and output.
- Isolation transformers: These provide electrical isolation between the input and output circuits, often used for safety purposes.
