Fault indicators for MV underground lines

Fault indicators for MV underground lines


The CableTroll indicators are fault current detectors for the underground medium voltage distribution network (6-36kV). They are used to detect short-circuit and earth faults and can be installed on most types of cable terminations. Some units will give separate indication for short-circuit and earth faults, locally by flashing diodes and remotely through separate relay contacts or additional ComTroll communication modules.
