WTT 216 - Power Generation/Transmission

Credits: 3
Lecture Hours: 2
Lab Hours: 2
Practicum Hours: 0
Work Experience: 0
Course Type: Voc/Tech
This course will serve as an introduction to the generation of electrical power with a wind turbine generator, moving that power through a local transmission system to a substation where a customer will purchase the generated power. This course will cover all aspects of working with components of a high-voltage transmission system.
Prerequisite: ELT 303 , ELT 131  
Prerequisite OR Corequisite: ELT 123
