Transformers I - Electrical Characteristics

This 1-hour interactive online course is the first part of a series of courses on electric distribution transformers. In this part we will look at the basic electrical characteristics of transformers including how magnetism is used to create a voltage within the transformer.

Characteristics such as how a transformer works, how the primary and secondary voltages and currents are related, how to calculate the transformer's regulation and efficiency, as well as the factors contributing to losses within the transformer are reviewed.

Diagrams are presented that show the basic construction of a distribution transformer and the course includes a description of the common designs in use today such as shell-form designs, core-form designs, and the various three-phase designs.

The course includes a multiple-choice test at the end.
