The CableTroll 2320/2330 indicators are fault current detectors for the underground medium voltage distribution networks (6-36kV). These indicators are used to detect short-circuit and earth faults and can be installed on most types of cable terminations.
These 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.
