This program presents fundamental concepts of power system design and operation in a user-friendly format that addresses the needs of non-electrical engineers involved in power service projects. It begins with basic electrical theory and demonstrates how these theories are applied when developing transmission and distribution systems.
Examples of recent power system events, transmission system limitations, and distribution system operating practices are presented in detail. "Show & tell" samples of a wide variety of power system components are displayed and discussed.
