    Function

    CLxx BLE is an overhead fault passage indicator, designed to be installed on the phase conductors (1 indicator per phase), that senses out of normal network mode in a single or 3 phase solidly earthed MV network. It helps the linemen to determine the origin of faults on the line.

    Key features

    CL 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.

    Streamer Fault Passage Indicator CL 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.

    Fault Passage Indicator CL 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 115 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

    Fault Passage Indicator CL 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.
