Nortroll is a world leader in finding faults fast and reducing outage times in MV distribution networks. Wherever on earth, whatever the challenge, we help saving time, energy and money.

Ever since 1977, we have developed innovative products for finding faults and controlling electricity distribution networks remotely.

Our range of overhead and underground fault passage indicators, called LineTroll and CableTroll, are used to track down the location of a fault - causing a loss of power supply to customers, as fast as possible. The indicators analyse the magnetic and electric fields set up by the fault current. When a fault occurs, the affected indicators are activated with a flashing light - with our control system you also send a fault message to the dispatching central.

Our range of remote control and monitoring equipment is called ComTroll. It is a modular system comprising RTU’s, outstations and base stations to provide remote monitoring and control of both overhead and underground switchgear. Designed to work with old existing switchgear or to be built into new systems, it is easy to install, operate and maintain whilst providing all the functionality of larger, more expensive SCADA systems.

With an integrated range of short-circuit and earth fault sensors, as well as remote control switching devices, the Nortroll system represents a new approach to automation of power distribution networks.

Nortroll systems are in use in more than 40 countries around the world, where the company is represented through appointed distributors.
