Relay technicians, system protection engineers, consultants, and engineers and technicians working in system protection can take this online course to expand their knowledge of protective relay systems. The course will benefit personnel of all levels of experience because it covers a range of complexity of relay schemes, methods of testing relays and of analyzing relay operations. ELO has partnered with the Electric Power Research Center (EPRC) to create a course that discusses basic system protection principles, measurement devices used for relaying, basic relay schemes used, and the most common schemes used in the field. Adapted from a live seminar from 2012, Tim Ernst, a system protection engineer, provides professionals with real examples from actual system protection situations.
