Distribution Transformer Fundamentals, February 26-27, 2019 in San Diego, CA

This course has been developed at the request of electric utilities and engineering consulting firms for their staff to gain practical experience with overcurrent protection on a typical distribution system.  The instructor was specifically selected for his skills at presenting complex distribution utility topics in a way that people can understand, remember and apply.  The 80/20 rule, Rules of Thumb, Best Practices, Lessons Learned, and Traps to Watch Out are just a few of the themes in this class.  He has been teaching over-current protection to engineers, trouble crews and linemen since 1998.  Over the years, veteran personnel from major fuse manufacturers have attended his training to get an end-user’s real-world perspective to fusing.

Instructor

Thomas Callsen, PE, Weldy Lamont

Thomas Callsen has over 30-years of related utility experience.   

During his 25-years at Commonwealth Edison Company (ComEd), Thomas held numerous engineering roles culminating as a Principal Engineer/Consulting Engineer in the Distribution Standards department where he was responsible for distribution transformers, capacitors, fuses, reclosers and distribution automation hardware.  In 2006 Thomas received DistribuTECH’s prestigious “Project of the Year Award” for his “Distribution Center in a Box” substation.  In 2009 he received the award again for industry’s first real-time overhead fault indicator communicating over a mesh network radio system.  (Both products are now commercially available.)  He received a US patent for the invention of the DC in a Box transformer design. 

In 2010, Thomas joined Weldy Lamont Associates where he is the Project Manager for a rural electrification project in West Africa.  This project includes construction of over 4,000 miles of overhead distribution lines serving over 2,000 rural communities in Ghana.  This project received the 2012 African Energy Award for the “Rural Electrification Project of the Year”.  Thomas has expanded his training to the electric utilities in Ghana where he has incorporated several of the industry’s best practices into the country’s overhead distribution line designs.

Thomas is a Senior Member of the IEEE and an active member of the IEEE Transformer Committee that writes the industry standards for transformers in North America.  Thomas holds a BSEE from the University of Wisconsin – Milwaukee and is a licensed Professional Engineer.
