Herrfors Nät-Verkko operates a distribution network where weather conditions frequently impact infrastructure reliability. Historically, identifying damaged components required extensive manual inspections, which were both time-consuming and costly.
To improve efficiency and strengthen grid reliability, the utility began collaborating with Safegrid in 2023 through a pilot project focused on advanced fault monitoring and localization.
The utility faced several operational challenges:
Difficulty in quickly locating faults after storms
Heavy reliance on manual field inspections
Increased costs and time spent on troubleshooting
Frequent vegetation-related damage, especially during storms
Risk of prolonged outages affecting customers
During strong summer storms in July, multiple trees fell onto 20 kV power lines, causing faults that required immediate response.
Safegrid deployed its Intelligent Grid System®, providing real-time fault detection and precise location data.
Accurate fault location identification
Real-time monitoring and alerts
Actionable insights for field crews
Fault locations were identified quickly and accurately
Actual fault points were within approximately 20 meters of Safegrid’s indicated locations
Maintenance teams were able to go directly to the fault site without unnecessary searching
The solution delivered significant operational advantages:
Early detection of hidden faults
Reduced need for extensive troubleshooting and inspection
Faster and more accurate fault diagnosis
Prevention of unplanned outages
Improved proactive maintenance capabilities
With Safegrid’s Intelligent Grid System®, Herrfors Nät-Verkko achieved:
Precise fault location within approximately 20 meters
Rapid response to storm-related faults
Faster repairs and restoration of power
Reduced operational costs
Shorter service disruptions for end customers
The collaboration between Herrfors Nät-Verkko and Safegrid demonstrates how advanced fault localization technology can transform grid operations, especially during extreme weather events. By replacing time-consuming manual inspections with precise, real-time data, the utility significantly improved response speed and efficiency.
This case highlights the value of intelligent monitoring in reducing downtime, lowering costs, and ensuring reliable power delivery even under challenging conditions.
