This is a Safegrid Case Study.
Background
Muonion Sähköosuuskunta operates in one of the most challenging environments in Finland. The network is located in Lapland’s Arctic region, characterized by:
-
Rough terrain and mountainous areas (fells)
-
Extreme winter conditions, with temperatures dropping to –20°C
-
Remote locations that make maintenance and fault finding difficult
In such conditions, even short power outages can have serious consequences for customers, making reliability a critical priority.
Challenge
The utility faced several operational challenges:
-
Difficulty locating faults quickly in remote and rugged terrain
-
Limited visibility into fault locations
-
Increased risk of prolonged outages in harsh weather
-
Multiple reclosing events before faults could be resolved
-
Need for better, data-driven decision-making
Traditional methods resulted in longer search times and inefficiencies during outage events.
Solution
Safegrid’s Intelligent Grid System® was introduced to provide real-time monitoring and accurate fault location.
Key capabilities:
-
Precise fault localization for faster field response
-
Real-time insights into grid behavior
-
Identification of fault recurrence across reclosing events
Incident example:
-
A permanent fault triggered protection relays and caused an outage
-
A delayed reclosing event also failed, indicating a persistent issue
-
Safegrid consistently pointed to the same fault location
-
Field crews were dispatched directly to the indicated area
-
A tree hanging on the overhead line was identified and removed
This targeted approach eliminated unnecessary searching and allowed for rapid resolution.
Benefits
The Safegrid solution delivered significant operational improvements:
-
Faster and more accurate fault location
-
Reduced need for repeated reclosing attempts
-
Improved grid reliability and resilience
-
Better decision-making based on real-time data
-
Increased efficiency in field operations
Results
With Safegrid’s Intelligent Grid System®, Muonion Sähköosuuskunta achieved:
-
50% reduction in outage time
-
Approximately 3 hours saved in fault search time
-
Fewer reclosing events required
-
Improved customer satisfaction and service reliability
“Safegrid has helped us to locate faults faster, reduce the amount of reclosing events, and shorten outage times.”
— Timo Rauhala, Operations Manager
Conclusion
Operating in extreme Arctic conditions requires advanced tools to maintain reliable electricity distribution. By adopting Safegrid’s Intelligent Grid System®, Muonion Sähköosuuskunta significantly improved its ability to detect and resolve faults quickly.
The result is a more resilient grid, reduced outage times, and better service for customers, demonstrating the value of intelligent monitoring in even the most demanding environments.
