APP 849: SEL-849 Motor Management Relay

Overview

This course is intended for electricians, plant operators, reliability engineers, electrical engineers and technicians, and industrial power system consultants.

Will your motors perform safely and reliably in today’s 24/7 process-integrated world? Increase your motor protection knowledge as you set and apply SEL-849 Motor Management Relays in a simulated low-voltage motor control center. In our hands-on lab environment, you will configure basic overload settings and test relay responses, including arc-flash detection. Learn to use the relay’s simple web server interface and Ethernet communications for real-world control operations. Predict potential problems by analyzing load reports, starting trends, and motor operating statistics to ensure safe, continuous motor function. Enroll now to learn how the SEL-849 can help protect your plant, your processes, and your personnel.
