Electrical Transformers CHANNEL

Electrical transformers are used to "transform" voltage from one level to another, usually from higher ac voltages to a lower voltages. They do this by applying the principle of magnetic induction between coils to convert voltage and/or current levels. There are various industrial power transformer types: there are oil-filled transformers and dry transformer types; there are underground transformers, pole mounted transformers, residential transformers and electrical power transformers. There is an auto transformer and a variable auto transformer. There is the...
