There are different types of transformers that are used depending on the application and requirements. Here are some of the most common types of transformers:
1. power transformers: these transformers are used in power transmission and distribution systems to reduce the voltage of high voltage lines to the low voltage suitable for consumption. They are used in power stations, substations and at various points in the electricity grid.
2. distribution transformers: These transformers are used to reduce the voltage of power lines to a level suitable for consumption in buildings or industrial plants. They are used in distribution systems to supply electricity to homes, offices and industrial plants.
3. switching transformers: These transformers are used in electronic circuits to increase or decrease the voltage. They are used in devices such as computers, televisions, audio amplifiers and other electronic devices.
4. isolation transformers: These transformers are used to isolate the energy transfer between two electrical systems and change the voltage at the same time. They are used in industrial, isolation and safety applications.
5. autotransformers: These transformers have a single winding that serves as both the primary and secondary winding. They are used to increase or decrease voltages and are used in devices such as voltage regulators, lamps and electric motors.
6. choke transformers: These transformers are used to limit and control the flow of current in circuits. They are used in electronic circuits, especially in inverters, rectifiers and frequency converters.
These are just a few examples of different types of transformers and their applications. However, there are many other specialized transformers for specific applications such as measurement and instrument transformers, impulse transformers, high voltage transformers, etc.
