Arva, a regional utility company operating in Northern Norway, is committed to delivering reliable electricity in a challenging climate and geography. As part of their strategy to modernize grid monitoring, Arva has deployed Safegrid’s Intelligent Grid System®. The goal is to gain better visibility into medium-voltage infrastructure and detect faults early before they escalate into outages.
Soon after the first sensors were installed in a specific area, Arva’s operations team observed partial discharge (PD) signals appearing in Safegrid’s system. Over the next day, the amount of signals increased.
Arva quickly dispatched a field crew to the coordinates indicated by Safegrid’s system. Upon arrival, the team confirmed consistent noise with PD activity. They identified a faulty insulator at the exact location.
“This was a great example of early detection. We saw the PD signals, sent our team out, and confirmed the issue onsite by ear. Safegrid helped us act before a real failure happened,”

Results:
- Verified detection of an active partial discharge from Safegrid’s solution.
- Faulty insulator located and replaced at the exact coordinates marked by Safegrid’s Intelligent Grid System®.
- Early warning capabilities help Arva prevent future faults proactively.
This successful case demonstrates the power of real-time monitoring in the field. With Safegrid’s Intelligent Grid System®, utilities like Arva can detect emerging issues faster, respond more efficiently, and build a more resilient electrical grid.
