Substation Fundamentals Sept. 12-13
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.
Learning Outcomes
- Review the basics of the power system
- Explore an in-depth section on substations covering their types and differences
- Describe the various components and all equipment in substations
- Review possible causes and solutions to substation faults
- Explain the various factors in and parts to substation safety
- Engage in an understanding of basic substation drawings and diagrams
-
List the components and tasks involved with managing a substation project

Introduction to Substation Design
September 13-14, 2023 | Online
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.
Learning Outcomes
A comprehensive introduction to the following substation components will be discussed:
- Review the various types of substations
- List substation reliability/redundancy considerations
- Review substation specifications and one-line diagrams
- Review site selection criteria and components
- Determine the keys to initial substation layouts
- Get an overview on civil engineering considerations including: concrete foundations, steel structures, and liquid containment
- Review substation components and ratings including: power transformers, voltage regulators, voltage regulating controls, overcurrent protective devices of fuses and circuit breakers, overvoltage protection
- List the purposes, uses for and types of protection & control
- Get introduced to metal enclosed substations
- Get introduced to modular substations
