Underground Electrical Distribution SystemsSee upcoming dates
This course will introduce you to the components in underground electrical distribution systems. We'll help broaden your understanding of the entire system and employee responsibilities, including planning, design, operation, and maintenance.
Learn from an industry-leading engineer in underground (UG) utility distribution cable systems (shielded cable, terminations, separable connectors, etc) and another in UG equipment and devices (transformers, switches, fuses, etc), both having a career's worth of application knowledge.
This course is intended to give all attendees a well-rounded understanding of electric utility primary UG distribution systems and the associated-organization responsibilities.
Who Should Attend?
You will benefit if you work in the areas of planning, design, construction, operation, maintenance, or safety of medium-voltage underground electrical distribution systems in a utility or institutional setting.

Mike Smalley has 28 years of electric utility engineering experience. The last 20 years focused on underground electrical distribution materials and standards, with a primary responsibility of low and medium voltage underground cable systems. He is a Senior Member of the IEEE Insulated Conductors Committee and a past Chair of the AEIC Cable Engineering Committee. He received a B.S. Degree in Electrical Engineering Technology from the Milwaukee School of Engineering, and a M.S. Degree in Engineering from the University of Wisconsin-Milwaukee. Mike is a Registered Professional Engineer in the state of Wisconsin.
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.
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.
Rogers is an electrical engineer with a background in electrical power systems. He is a registered professional engineer, and his 18 years of industry experience spans across electric utility, government, commercial, and industrial applications. His technical responsibilities have included design and commissioning of mission-critical facilities, underground medium voltage distribution planning, design, and operations, high-voltage substation design, and relaying protection and control for complex interconnections. Prior to joining EPD, Rogers spent his previous 5 years as the Engineering Manager for an electrical engineering consulting firm where he and his colleagues provided diverse engineering services across the electrical construction industry.
