Distribution Transformers

Paper Summary:

This paper begins with an explanation of what transformers are and a description of their function and construction. The paper also explains the different types of transformers, describes the history of transformers and provides an overview of distribution transformers. Finally, the paper talks about the dangers associated with the repair and maintenance of transformers and what can be done minimize those dangers.

From the Paper:

"In a transformer, the primary coil is fed by an alternating electric current, which creates a magnetic field around the conductor. The secondary coil, which is placed in the varying magnetic field, develops a potential difference that is referred to as an electromotive force (EMF). EMF refers to the force, measured in volts, produced by the interaction between a current and a magnetic field. EMF can also be referred to as electrical potential or potential difference. When the ends of the secondary are connected to form a circuit, the EMF causes a current to flow in the secondary coil. By this method, electrical power that was fed into the primary is delivered to the secondary ("Transformer"). The EMF developed in the secondary coil is "proportional to the ration of the number of turns in the secondary coil to the number of turns in the primary coil" ("Transformer"). The electrical power in the secondary can then be distributed outside of the transformer."
