IT'S GOOD TO KNOW WHERE THE FAULT IS Locating transmission line faults can be costly and time-consuming. Since 1984, when SEL introduced the first digital relay with fault location, we have continued innovation of this important feature. With the introduction of the SEL-411L Advanced Line Differential Protection, Automation, and Control System, we created the only relay with traveling wave fault location to make it easier than ever to accurately pinpoint faults. Save time and money by sending maintenance crews to the tower nearest the fault, and get the line back in service faster.
