This WEBCAST course is comprised of six 4-hour modules.
This course provides students with a working knowledge of electric power systems from a dispatcher's perspective. The information provided in this course is designed to cover all the essentials needed to properly direct the day to day activities of a power dispatcher's control desk. Upon completion of this course, the student will be able to discuss electrical fundamentals, describe the operation of substation equipment, explain distribution systems including consumption, describe protection and telecommunications principles, apply electrical safety essentials and demonstrate knowledge learned through proper dispatch and energy control practices.
