Smarter network management

NORTROLL reduces the costs related to power supply interruptions by offering equipment for fault detection and remote control of Medium Voltage distribution networks.

Nortroll gives the operation manager powerful decision and analytical tools so that he can make a fast and correct decision, and perform a corresponding action. The products improve the operators' efficiency and responsiveness. The products monitor the distribution network and send data to the control centre. The faulty parts of the sections can be easily identified and quickly disconnected. Remotely operated switchgears reconnect the healthy sections of the network in a very short time.

The equipment ensures safe and stable power supply, with reduced outages.
The utilities that have invested in Nortroll equipment testify: the sectionalizing time has been reduced from days and hours to only a couple of minutes.
