Distribution Over-Current Protection – Fuses and Reclosers, August 27, 2020 in Denver, CO

This course has been developed at the request of electric utilities and engineering consulting firms for their staff to gain practical experience with distribution transformers.  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.  The real-world examples and practicality of this course will save the students from countless errors down the road. 

This course is intended to be a hands-on, practical course for engineers and consultants. The main purpose of this course is to provide attendees with the knowledge that they need in order to make informed decisions regarding transformer sizing and selection as well as who the major vendors are. The intent of this course is to help companies save time and money. This course will provide attendees with reference materials that they will be able to continually go back to for guidance long after the course is completed, however, this course is not “death by power point” and will encourage discussion and allow attendees to customize the training to meet their educational needs.

Instructor

Thomas Callsen, PE, Project Manager, Weldy Lamont Associates

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.
