eRLY 102: Relay Front-Panel Operations

This complimentary eLearning course teaches new users how to operate SEL relays using the front panels. It provides an overview of the key components and functions of SEL relay front panels. You will learn how to view and retrieve data, change settings, interpret front-panel LEDs, and perform control functions directly from the front panel. Through simulated, hands-on practice exercises, you will navigate front panels using either a touchscreen or LCD and pushbuttons.
