CBT 751: Introduction to the SEL-751/A Feeder Protection Relays


This course is intended for utility and industrial protection engineers and power system consultants.

CBT 751 provides training for the SEL-751 and SEL-751A Feeder Protection Relays, which are extremely versatile protective relays used worldwide for industrial and utility feeder protection. This self-paced training provides an introduction to feeder protection using the SEL-751, including front-panel navigation and displays, acSELerator QuickSet SEL-5030 Software, relay logic, and arc-flash detection. Learn basic feeder protection principles and apply recommended settings for comprehensive overcurrent protection.

Use CBT 751 as stand-alone training covering the basics of SEL-751 Feeder Protection Relay operations, protection functions, and settings. This training also prepares you for attending APP 751, a two-day, hands-on application course. CBT 751 is included in the APP 751 course price.

This course is designed as a half-day program but is self-paced.
