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

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 standalone 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.
