Protective Relaying Principles & Applications

Learn the fundamental concepts of protective relaying starting with basic and advanced to important setting considerations, and eventually ending with a discussion of fault and disturbance analysis. Gain confidence in your ability to recognize key protective relaying considerations for distribution lines, transmission lines, substations, transformers, buses and circuit breakers.

This course can be applied to the Electrical Engineering Certificate.

Who Should Attend

Analysts, designers, engineers and technicians involved with the design, development or utilization of transmission lines, distribution lines, substations or medium voltage motors as well as anyone involved in protective relay selection and application.

Benefits and Learning Outcomes

  • Know criteria used to select protective relay settings
