Three-Phase Transformer Connections

Phase angle. Vectors. Loading transformers properly.

These are some complicated principles. Which is why we bring in Scott Meinecke to instruct. Scott is with the Iowa Association of Electric Cooperatives and has more than 25 years experience as an instructor on this topic. Scott has a way of explaining things so you can understand it and he keeps everyone engaged.

At this workshop, you'll take Scott's instruction and apply it to the bank of miniature transformers. Working in small groups, you'll troubleshoot a variety of single phase and 3-phase scenarios. Once you've fixed the problem, you can test it and see first hand what worked and what didn't work!

The Transformer School offers the ultimate combination of classroom and hands-on training that can help improve your understanding of the inner workings of a transformer, appropriate installations and applications for maximum reliability. In addition, we offer a Pre-Conference covering basic single-phase transformer connections and theory. (Separate registration required.)

This program can benefit any lineworker—wherever you are at in your linework career.

What You Will Learn

The three-phase course will start with the basics of transformers, including turns ratios, polarities, calculations, connections, and troubleshooting. Participants will learn about the basic three-phase systems with some basic phasor diagrams and explain the relationship of the phasor to the transformer itself.

In the hands-on portion of the course, participants will work with miniature transformers that are energized and will blow fuses, in order to experience what happens when something is wired incorrectly.

The class will continue to build on the miniature transformer banks and work on troubleshooting. Additionally, they will discuss motor rotation as it relates to three-phase systems; as well as ways to prevent voltage surge when switching a three-phase bank.

Upon completion of the Three-Phase Transformer Connections class, participants should have a good understanding of the following topics, related to transformers:

Basic Three-Phase Connections
Delta Connection
Wye Connection
Open Delta Connection
Three-Phase Troubleshooting
