SEL-BTRIP

Overhead BEACON Field-Programmable Timed-Reset Fault Indicator

The SEL-BTRIP is designed for 4,160 V to 69 kV overhead system applications. It is quick and easy to apply using a single hot stick. A super bright flashing LED display provides clear indication of an overcurrent event. The SEL-BTRIP is completely powered by a 3.6 V high-capacity 8.5 Ah lithium battery with a 20-year shelf life.

The SEL-BTRIP is available in five program selection choices, each containing four field-selectable nominal trip ratings. Specify which program setting is to be factory-set, or select/change the nominal trip rating in the field using the CRSRTT tool. The SEL-BTRIP’s versatility and efficiency make it useful in locating momentary fault occurrences or as a permanently installed fault indicator. No maintenance is required.

Troubleshooting for Overhead and Underground Lines—Field-select one of four fixed trip values: 50 A, 100 A, 200 A, or 400 A. Use lower trip values at the ends of circuits due to lower available fault currents. Use higher nominal trip ratings near the substation. Conveniently keep SEL-BTRIPs on the truck. Temporarily apply the SEL-BTRIP at key points along the circuit to troubleshoot a fault. Remove the SEL-BTRIP after the fault is located.

Timed-Reset Intervals—Manually reset the SEL-BTRIP using the CRSRTT magnet test tool so that units can be reapplied to another part of the circuit to further narrow down the faulted circuit section. If you don’t have the opportunity to reset the units, designate a four-hour timed-reset interval, and the units will clear after four hours to conserve battery life.

SEL-BTRIP benefits include: 

  • Field-selectable nominal trip rating based on circuit load and available fault current—stock one fault indicator for a variety of system conditions.
  • Clear visual indication of the fault path to line crews in the field.
  • Reduced fault-locating time by guiding line crews to the faulted line section.
  • A simple, economical way to improve utility reliability metrics by reducing outage durations.
  • Inrush restraint feature for coordinated integration with automatic reclosing schemes, preventing false tripping.
  • Rugged construction that ensures a long product life.
  • Quick, simple installation:
    • Installs with a single hot stick—no extra clamps or screws.
    • Zero maintenance.
    • Tests and manually resets with the CRSRTT tool.
