Fault indicators for MV or HV overhead lines
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.
