Introduction to Transmission and Distribution Systems
COURSE DESCRIPTION
This course explains, in general terms, how transmission and distribution systems deliver power from a power plant to customers. The course describes the major components of a typical T&D system, how they function, and how electricity flows through these components on its journey from the power plant to customers.
COURSE GOAL
Describe how transmission and distribution systems generally operate.
Identify the basic components of a transmission and distribution system and explain their functions.
Describe the flow path of electricity from a power plant, through a typical T&D system, to the customer.
