Power Transformer Applications

Power transformers are used for many applications including to step down the high transmission voltage in power lines to a level that can be used by industrial business and household usage.  Transformers are designated by low, medium and high side operating voltage, and sized by the capacity of the volts and amperes being carried.  The power transformer has been the backbone for the electrical distribution system for many years.  Power transformers are extremely reliable and are known for their high efficiency.

Power Distribution Utilizes Power Transformers

In the distribution of electrical power, the power transformer works two ways; 1) it transform the voltage up to a higher level at the generating source, then the electricity travels via transmission lines at this high voltage level to its destination where it is then transformed, lowering the voltage back to a lower level for use in business industries and homes.  Power transformers convert an alternating current power to a voltage supply that is compatible with electronic devices, such as electric motors, cell phones, telephones, answering machines, computers, radios and etc.  Power transformers are used to change electric voltage and thus they also reduce the dependence upon batteries and provide charging energy for rechargeable batteries from available alternating current power supplies.

Power Transformer Physical Makeup

Power transformers usually consist of insulated copper wire (or aluminum wire) wound on an iron core and consist of two windings which is referred to as a primary winding and a secondary winding.  In a toroidal power transformer, a primary winding is first wound on a toroid (doughnut) shaped core, covering nearly the entire circumference of the core.  One or more secondary windings are then wound on top of the primary windings, with a high-voltage insulating layer separating the primary and secondary windings.

The insulation layer provides a protection layer capable of withstanding high-voltage insulation testing and high operating potential differences between the primary and secondary windings.  Power transformers also use paper or cellulose materials insulation positioned between or around the various conductive paths.  Mineral oil is also commonly used as an insulator in power transformers which also works as a coolant.
