APP 411L is an advanced hands-on course that builds on the introductory configuration and protection principles taught in CBT 101, CBT 421, and APP 421 as well as the logic configuration principles taught in CBT 104. Students in APP 411L will complete hands-on exercises to configure differential protection and advanced logic.
APP 421 provides comprehensive application instruction for the SEL-421 Protection, Automation, and Control System, an extremely flexible, high-speed relay for dual-breaker control applications used in multiple functions. Students (in groups of two) will work directly with the SEL-421 to gain hands-on experience in communicating, setting, metering, monitoring, reading event reports, retrieving event reports, and performing control functions.
