Transformers play a critical role in the electrical power system. Their primary purpose is to provide electricity at voltages levels that are appropriate for a specific application. In some cases, the application will be for the transmission or distribution of electricity, and will ultimately lead to providing electrical service at a useable levels for the end user.

Transformers play an important role in the power system. They help convert power to appropriate levels which other components can safely use. They are often in operation for a long time and only stop working during power interruptions and maintenance. Due to the stress they take, it is important to regularly assess their functions to ensure continuous service.
