ePROT 200: Applied Symmetrical Components

Course Length: 13 Hours (PDHs: 13)

Course-Based Fees: $800*

*Plus Applicable Tax

Description

Symmetrical components knowledge is an essential tool to understanding faults in the power system and how digital protection algorithms work. In ePROT 200, students will learn the fundamentals of symmetrical components, be exposed to theoretical and real-world examples to help them gain experience with the method, and apply that knowledge to analyzing and troubleshooting faults and problems on the power system.

Audience

Utility and industrial engineers and technicians who need to learn about the fundamentals of symmetrical components and how they are used to calculate fault currents and commission protective relays would benefit from this eLearning course.
