Instructor: Michael Godfrey
Course Credits: 24 CEHs and 24 CTDs – The Power Systems Seminars have been approved by the Florida Board of Professional Engineers for CEHs.
Overview: Relay Testing and Commissioning Intermediate is an interactive seminar designed to teach relay technicians and electrical systems commissioners new techniques and approaches to protective relay testing and protection systems commissioning. The course is aimed at personnel with between 2 and 5 years of related experience and may provide benefits for personnel with fewer or greater years of experience. The course combines in-class lecture, group activities, guided instruction and a hands-on lab.
The lab is highly interactive, as it gives participants the opportunity to review the equipment that would normally be used to protect and control electrical power systems. The lab stations contain a sample relay, breaker simulator, and relay test set.
Target Attendees: Industry professionals with intermediate experience in electrical protection and control, protective relaying, and system design that are interested in adding to their electrical protection testing, commissioning, and calculation abilities. Ideal candidates will have between 2 and 5 years of related field experience.
Recommended Prerequisites: Participants should have taken the Relay Testing and Commissioning Basic class or have an equivalent level of experience. Participants should be comfortable with power math principles and a wide range of calculation methods.
