    Product description

    Line Fault Indicator (LFI) is an intelligent power monitoring device designed to detect and locate line faults such as short circuits and grounding faults in real time. It assists maintenance personnel in rapid response, reduces power outage duration, and enhances power supply reliability. Suitable for various applications including 10-35kV overhead lines, underground cables, substations, and new energy power stations.

    MAJOR FUNCTION

    High strength and high perspective aviation materials are used for one-step molding, and treated by nanotechnology. 
    The perspective is better, anti pollution, anti-aging, free protection, and long service life 
    ① High performance battery, with a service life of over 8 years. 
    ② A circuit board composed of imported components such as specialized chips and microcontrollers. 
    ③ Shell made of aviation and nanomaterials. 
    ④ After nickel plating treatment, it has strong magnetic conductivity. A card wire structure that can be installed with 
    electricity. 
    ⑤ Using red fluorescent paint, it has a strong visual effect and can be clearly indicated under night light. 
    ⑥Display rotations that do not fade under long-term outdoor ultraviolet radiation.

    OPERATIONAL PRINCIPLE

    1

    Short circuit detection principle: 
    According to the phenomenon of short circuit, during the moment of short circuit, the current suddenly changes and the 
    protection action loses power as the basis for action. 
    Schematic diagram of fault indication used to determine short circuit: 
    It can be determined that a short circuit fault has occurred at the exit point by flipping the red signs on the daily phase 2, 
    5, 8 indicators of Line 2, and the 3, 6, and 9 indicators of Phase C of Line 2, while the 11 and 12 indicators are still white.
