From professionals – to professionals. Our goal is to enhance and improve our portfolio to meet customer needs and market potential.

Over the years, Nortroll has established a very strong brand. Our three recognised product lines are listed to the right.


Fault Passage Indicators to locate short circuit and earth faults.


Fault current indicators for the underground medium voltage distribution network (6-36kV).


A modular system with different building-blocks allowing the utilities to tailor-make a system.

Covid-19 coronavirus information to our customers and partners

Nortroll AS is actively and continuously monitoring the Covid-19 coronavirus outbreak, in line with local and national authorities and public health advice and WHO guidelines..

The health and safety for our customers, distributors and our staff are our number one priority. Nortroll AS will remain in full operation during these challenging times. But we have taken measures in order to limiting the spread of possible infection and have introduced the following guidelines.

  • Critical service assignments needed to ensure the supply of energy for our customers can be agreed and must be approved by both parties. Travelling shall not be done on public transport, only by own car.
  • Traveling out of Norway for all our employees is suspended until further notice.
  • Meetings internally and externally shall be done by teleconference.
  • To keep the production running as normal we have split our team in two. In the event of a possible infection detection at Nortroll we have limited the risk and avoid that all personnel must go into quarantine.
  • All employees with the possibility to work from home are instructed to do so.

With these measures we hope to be fully operational through this period. We will respond to customer enquiries, perform service and support, and also deliver goods from our warehouse as usual.
