A transformer is an electrical device used to convert high voltage or high current into low voltage or low current for the purpose of measurement and protection of power systems. Transformers typically consist of a core and coils, with the coils wound around the core. When the current or voltage passing through the transformer changes, the current or voltage in the coils also changes accordingly. This change can be measured and recorded to monitor the status and performance of the power system.
The main function is to ensure the safety of equipment and personnel by converting dangerous high levels into manageable low levels. They also trigger protective devices when faults occur, ensuring stable operation.
