APP 751: SEL-751 Feeder Protection Relay


This two-day course is intended for utility and industrial protection engineers, and power system consultants.

APP 751 provides complete application training for the SEL-751 Feeder Protection Relay, which is an extremely versatile protective relay used worldwide for industrial and utility feeder protection. Students (in groups of two) will gain hands-on experience in communicating, setting, metering, monitoring, retrieving event reports, and performing control functions, working directly with an SEL-751 Relay.

CBT 751 precourse training is included in the price of the course.
