    JYZ-FF Remote Overhead Fault Indicator

    The JYZ-FF-C (indicator) & JYZ-FF-HD (data concentrator) Remote overhead Line Fault Indicator (RFI)is used in 5~38KV overhead line networks, enable the electricity distribution network engineers to quickly identify the faulty section of network and restore power supplies to customers on healthy sections in the shortest time possible. 
     
    A high accuracy current sensor in the JYZ-FF-C line fault detector, monitors the phase current flowing. When detecting current level exceeds a user-selectable threshold (as a result of a phase-to-phase or phase-to-ground fault), the fault is indicated by mechanical Flag and flashing, high-power LED, and at the same time send the fault message to the JYZ-FF-HD. The JYZ-FF-HD will transmit the data to the central monitoring station over the cellular network. Combined with GIS and SCADA, the central monitoring station could accurately locate the faulty section and send the maintenance crew man to the faulty section for troubleshooting.
     
    The fault is located between the last Indicators that has been triggered and the first one which is still inactive. The path of the fault current from the feeding point to the fault location is marked by the triggered indicators.
     
    The unit of line fault detector resets is optional either automatically when power to the line is restored, or after a user-selectable timer period, or could manual remote reset from ground level.
     
    The fault passage indicators can be mounted under live conditions with the help of an adapter and a hot stick. The Electric Fault Indicator could be self-sustained by the monitored network from a current flow of 10A upwards. The line fault indicator also with built-in lithium battery that could powered the fault locator for more than 10 years.
