Course Outlines

Transformers I - Electrical Characteristics

One Hour

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.  You must have Flash Player Version 7 or higher to view some parts of this course. We also recommend you view this course in Internet Explorer.

Transformers II - Standards

Two Hours

This 2-hour interactive online course is the second in a series of courses on electric distribution transformers.In this course we will review the various methods to classify transformers including cooling methods, protection schemes, and installation types.This course discusses transformer types, including oil filled and dry types, as well as the different types of transformer oils that are used. Both conventional and CSP transformers are reviewed.Standards, such as the insulation standard, short-circuit withstand, voltage rating identification, and terminal markings, are reviewed.

Finally, transformer loading issues and methods to evaluate the cost of operating distribution transformers are discussed.The course includes a multiple-choice test at the end.You must have Flash Player Version 7 or higher to view some parts of this course. We also recommend you view this course in Internet Explorer.

Transformers III - Connections

Two Hours

This 2-hour interactive online course is the third in a series of courses on electric distribution transformers.  In this course, we review the application of single-phase transformers in both single-phase installations and three-phase installations. Other factors such as the available fault current at the secondary of a transformer are reviewed as well as how ferroresonance impacts the operation of distribution transformers. The course includes a multiple-choice test at the end. 

You must have Flash Player Version 7 or higher to view some parts of this course. We also recommend you view this course in Internet Explorer.
