  • Measured/monitored value:

    phase sequence

  • Other characteristics:

    multifunction, transmission line

Advanced Line Differential Protection, Automation, and Control System
Apply the SEL-411L Relay for complete protection and control of any transmission line. The SEL-411L provides differential protection with both phase- and sequence-based operating elements for sensitivity and high-speed operation. Choose from many popular fiber and multiplexed communications options. Distance protection and logic from a complete SEL-421 Protection, Automation, and Control System are included to provide backup protection and integration. Any transmission line (short, long, or series-compensated) can be well protected with the SEL-411L Relay.
