An In-Depth Look at Electricity’s Journey from Source to End-Use Consumer

Electricity takes a complex journey from its original generation source to its end-use destination. Electric System Fundamentals gives a tour of the physical electrical system from the generator to the customer meter. The course explains common industry jargon and the basic physical laws of electricity, how generators work, which generation types are commonly used and why, the components that make up transmission and distribution systems, how transmission and distribution systems are designed and operated, the different types of service configurations and when they are used, and how electricity is metered.                                                                                                                                                                                                 

This course comprises the following modules:

  • Introduction
