Cable Indicators

The Cable Troll indicators are fault current indicators for the underground medium voltage distribution network (6-36kV).

They are installed on Ring Main Units in distribution substations. 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 indications for short circuit and earth faults, locally by flashing diodes and remotely through separate relay contacts or additional ComTroll communications modules.

Remote indication

All of our Cable Troll fault indicators have a relay output for interfacing with equipment that can forward the alarms to a control center, SCADA system or a cell phone.

NorTroll offers a wide range of communication modules and RTUs with various communication options such as radio, GSM, fibre, Ethernet etc.
