Power transformers adjust the voltage between different parts of an electrical system to allow it to operate. The main parts of a transformer are the iron core and the coils, although others components ensure optimal functionality. Copper and iron losses affect the transfer of power between high and low-voltage terminals in a transformer. This chapter revises the equivalent circuit and operating modes of power transformers.

Power transformers adjust the voltage between different parts of an electrical system to allow it to operate. The main parts of a transformer are the iron core and the coils, although others components ensure optimal functionality. Copper and iron losses affect the transfer of power between high and low-voltage terminals in a transformer. This chapter revises the equivalent circuit and operating modes of power transformers.
