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).

Our way of working has made us into a leading supplier and an appreciated employer.

Professional colleagues with passion for their work, responsibility, competence and courage to think anew, thus experience the joy of driving development forward. We are a team that makes things happen and at the same time, having fun together is not far from our minds!
