Substation Fundamentals
September 10-11, 2024 | Online
I have a better understanding of substations than anticipated. I am a lot more confident in my abilities to manage a substation project.” Project Coordinator, Lubbock Power & Light
“EUCI courses have three fundamental characteristics: substance, substance, and substance. Time and money well spent.” Assistant GM-Power Supply, Burbank Water and Power
“This was a very good course for someone with my experience and knowledge. I learned a lot about substations and feel like I have a more well-rounded knowledge of substations.” Civil Engineer, Shive-Hattery
This course will introduce and provide non-technical people with the basics of a substation and all the general components that are inside a substation. General issues that are involved in the construction, operation and maintenance of substations and switchyards, and detailed safety awareness will be discussed. It will allow people who are not substation design engineers to know enough to oversee various aspects of a substation and will allow strong oversight of contractors and various substation projects.

Introduction to Substation Design
September 17-18, 2024 | Online
“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
“It gave me an insight of what we are using at our present company and what other technology is on the market and the benefits. It was very informative.” Trainee Engineer, Belize Electricity Ltd.
“EUCI set you up with an extensive framework and encourages all participants to dive deeper in to individual topics for further personal development and understanding.” Engineer, Prairie Land Electric Cooperative
“This course was very informative. The subject PowerPoint and materials are very detailed and well put together.” Senior Electrical Engineer, FFE Inc.
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.
