Applications

Overhead

• Provides clear visual indication of the fault path to line crews in

the field.

• Reduces fault-locating time by guiding line crews to the faulted line

section.

• Allows line crews to easily distinguish between temporary and

permanent faults.

• Provides a simple, economical way to improve utility reliability

metrics by reducing outage durations.

Rural

• Automatic trip value selection as low as 50 A.

• TR(TV)

feature (Timed Reset as a function of Trip Value) allows

additional time for line crews to find faults on remote lines.

Troubleshooting

• Distinct eight-hour temporary indication leads line crews to

troubleshoot problematic sections of line.

• Allows line crews to investigate the cause of self-clearing faults and

successful trip and reclose operations to improve circuit reliability.
