Training
APP 751: SEL-751 Feeder Protection Relay
Description
This course 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. You will work with an SEL-751 to gain experience in communicating, setting, metering, monitoring, retrieving event reports, and performing control functions.
Audience
APP 751 is intended for utility and industrial protection engineers and for power system consultants.
