“This course was a perfect next step for an electrical engineer working in the utility sector. Learning about substation design methodology and terminology has provided a baseline and logical next step in building my professional skillset.” Electrical Engineer II, City of Boulder

Transmission to distribution substation designs vary in complexity, proportional to their rating (MVA) and application. A variety of engineering disciplines are involved including civil, mechanical, electrical power and communications. Design philosophies are influenced by a utility’s contingency strategy, space limitations, aesthetic requirements, work rules, maintenance practices, and other factors.

This course will provide an overview of design methods with given specifications and a one-line diagram for a typical T to D substation. Discussion concerning substation device options provide attendees with the information to make intelligent choices regarding design features. The class creates a forum for comparing best practices for substation design, maintenance, and the operation of these facilities.
