    Function

    Lodestar CL2 (and CL0.5) is an overhead line fault indicator conductor mounted helping the linemen to determine the origin of faults on the line. Powerful white and red LEDs allow them to locate faulty sections in bright daylight. Thanks to Remote control, users can access logs of events on the line, instant current values and settings of the device.

    Key features

    Lodestar Fault Indicator senses current on the phase where it is installed. Indication is triggered when it detects a faulty current, above the current threshold, passing in the line conductors.

    Lodestar is designed as not to react on inrush current. So-called inrush resistance is the parameter, which helps to restrain triggering due to transformer’s magnetizing current or switching a load.

    Lodestar is equipped with Radio Frequency (RF) channel and memory capabilities to allow connection to cloud monitoring and fault location system, as well directly to SCADA.

    Networks

    • 6 to 110 kV
    • Insulated, compensated or effectively grounded neutral
    • 3 wires (3 phases)
    • 4 wires: 3 phases + ground wire
    • Bare or covered conductor with external diameter of 5-40 mm
    • Steel, concrete or wooden poles

    Installation

    Lodestar is designed to be installed on bare or covered conductors up to 40 mm external diameters (equivalent to 240 mm2 with insulation thickness of 7 mm). One indicator per phase is required.

    Lineman can use hotstick adapter to install FI on live line without switching off the line.
