Transformer Theory and Calculators
Transformers change AC voltages. They change voltage by stepping up the primary voltage on the secondary side or stepping down the voltage. They are also used to match impedance and as isolating devices that isolate the ground. A.C. is required to operate transformers because the voltage induction that occurs between the primary and secondary requires a rapidly expanding and collapsing electromagnetic field that only alternating current provides. Electrical power transmitted as high voltage has a reduced current. Smaller cable sizes can be used. The cost effectiveness of smaller cables is the reason for high voltage distribution but it must be stepped back down for consumer safety. |
