LineTroll 111K - Utility pole mounted fault indicator for  6-66KV transmission lines

THE MONEY-SAVER
Minimize duration of blackouts. Reduce number of fault reclosures, reduce wear and tear. Works with single- and 3-phase line configurations.

VERSATILE
User configuration of fault sensitivity, trip and reset parameters. Extended reset time with low-power LED indication. Automatically adapts to load current (di/dt). Optional output relay contacts for connection with RTU’s and HMI.

EASY TO MOUNT

Mount the indicator 3m below transmission lines. No special tools required. Reducing the total mounting costs.

HIGH VISIBILITY
Omni directional Xenon tube flash-light. Specially designed lens for easy long distance monitoring.

HOW IT WORKS:
Linetroll 111K contains magnetic and electric field sensors - sensing line current and line voltage. The magnetic sensor automatically adapts to line current, when di/dt increase rapidly the sensor will detect the overcurrent. The electric field sensor also monitor the presence of voltage potential. The sensor signals are processed and compared with a set of alarm criteria's configured by the user.

When a line fault (that fulfills the alarm criteria) occurs, all indicators installed between the feeding point and the fault location will signal an alarm.

A Xenon light indicates the passing fault current by releasing a omni-directional high intensity flash.

INSTALLATION:
Linetroll 111K is fitted on a utility pole 3 - 5 m below transmission lines, check the User Guide for details.

Linetroll 111K mounts with screws (included) or wrapping bands.

Linetroll 111K is easily tested with a magnet after installation.
