Fault indicators for MV or HV overhead lines

LineTroll Fault Passage Indicators are used to locate short-circuit and earth faults in MV/HV overhead line distribution networks. LineTroll product line will fully cover the different fault configurations that may occur. The indicators are placed at strategic locations along the line such as after branching points and sectionalisers. Depending on the type, the indicators are mounted on the conductors or on the pole, 3-5 meters below the conductors. Live line mounting is done safely, easily and rapidly. LineTroll fault Passage Indicators fault sensing is based on detection of the electromagnetic field below the conductors. Upon detecting a fault on the line, the indicator gives off an intermittent LED and/or Xenon type flashing. The unit is fully self-contained, no external transformers or connections of any kind are required.
