Core form = core type; shell form = shell type
Closed-core transformers are constructed in 'core form' or 'shell form'. When windings surround the core, the transformer is core form; whe… See more

Transformers can be classified in many ways, such as the following:
• Power rating: From a fraction of a volt-ampere (VA) to over a thousand MVA.
• Duty of a transformer: Continuous, short-time, intermittent… See more

Various specific electrical application designs require a variety of transformer types. Although they all share the basic characteristic transformer principles, they are customized in construction or electrical properties f… See more

Electromagnetic induction, the principle of the operation of the transformer, was discovered independently by Michael Faraday in 1831 and Joseph Henry in 1832. Only Faraday furthered his experiments to the point o… See more
