Instructor: Michael Godfrey
Course Credits: 24 CEHs and 24 NETA CTDs – The Power Systems Seminars have been approved by the Florida Board of Professional Engineers for CEHs.
Overview: Relay Testing and Commissioning Basic is an interactive seminar designed to teach relay technicians and electrical systems commissioners the basics of protective relay testing and protection systems commissioning. The course is aimed at personnel with between 6 months and 2 years of related experience but can be taught to those just entering the field. The course combines in-class lecture, group activities, and hands on experience with protection system equipment. This course is intended to be manufacturer agnostic and does not go into depth with specific relay models or testing software suites. In addition to the core learning material, attendees will spend time learning important fundamentals of power math, electrical phasors, and symmetrical components. Participants in the class will leave with an excellent foundational understanding of the work that goes into protection and control systems design, creating commissioning plans, and using a strategic approach to relay testing and troubleshooting.
Target Attendees: Industry professionals with minimal experience in electrical protection and control, protective relaying, and system design that are interested in learning more about the process of testing protection and control systems, commissioning electrical protection schemes, and calculating steady state electrical values. Ideal candidates will have between 6 months and 2 years of related field experience.
Recommended Prerequisites: This is a foundational course and there are no mandatory prerequisites. Participants should be familiar with basic algebra and trigonometry, as well as DC circuit theory and working principles (such as Ohm’s Law, and Kirchhoff’s circuit laws). It is helpful if participants are familiar with the human performance mindset and should have some knowledge of HP error traps, mitigation techniques, and tools.
