Three-phase transformer connections

Scott Meinecke is an expert on transformers and will be back to instruct. Scott has been training on the topic for more than 25 years, and he is known for explaining complicated principals in such a way that they can be more easily understood. The combination of classroom and hands-on instruction is designed to increase 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.)

Transformer School, taken in conjunction with the Pre-Conference, offers an exceptional hands-on training experience.

NOTE: Members of MREA need to register on their site directly.

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
