| Project Overview | Arva, a regional utility in Northern Norway, deployed Safegrid’s Intelligent Grid System® to enhance visibility across its medium-voltage network. By leveraging real-time monitoring and partial discharge detection, Arva was able to identify a developing fault early and take immediate action—preventing a potential outage and strengthening grid reliability. |

Operating in Northern Norway, Arva manages a distribution network exposed to harsh weather conditions and challenging terrain. Ensuring reliable electricity delivery in such an environment requires advanced monitoring capabilities and proactive maintenance strategies.
As part of its grid modernization efforts, Arva introduced Safegrid’s Intelligent Grid System® to gain deeper insights into network conditions and detect hidden faults before they escalate.
Arva sought to address several key challenges:
Limited visibility into early-stage faults in the network
Risk of undetected insulation issues developing into outages
Need for faster, data-driven fault identification and response
Harsh environmental conditions increasing stress on grid components
Shortly after deploying the system, Arva observed increasing partial discharge (PD) signals, indicating a developing issue that required immediate investigation.
Safegrid’s Intelligent Grid System® provided real-time insights into grid behavior and flagged a PD hotspot.
Continuous monitoring detected rising PD activity
Precise location data enabled rapid dispatch of field crews
On-site inspection confirmed audible PD-related noise
A faulty insulator was identified exactly at the location indicated by Safegrid
Immediate corrective action was taken to replace the component
“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,”
— Inga Setså Holmstrand, Network Analyst, Arva
The deployment delivered significant operational advantages:
Early detection of developing faults
Accurate fault localization, reducing inspection time
Faster and more efficient field response
Reduced risk of unexpected outages
Improved grid resilience and reliability
With Safegrid’s Intelligent Grid System®, Arva achieved:
Verified detection of active partial discharge signals
Precise location of a faulty insulator at identified coordinates
Successful replacement of the defective component before failure
Strengthened proactive maintenance capabilities
This case demonstrates the power of real-time monitoring and early fault detection in modern grid operations. By leveraging Safegrid’s Intelligent Grid System®, Arva transitioned from reactive troubleshooting to proactive maintenance—detecting and resolving issues before they could disrupt service.
The result is a more reliable, efficient, and resilient electrical grid, capable of meeting the demands of challenging environments while ensuring continuous power delivery.
