Founded in 1900, Porvoon Sähköverkko operates a 3,700 km distribution network serving over 37,000 customers. Located along Finland’s coastal region, the utility frequently faces strong winds, storms, and challenging weather conditions, which can damage infrastructure and disrupt power supply.
To maintain high reliability and customer satisfaction, the utility sought to improve its fault detection capabilities and minimize outage durations.
Porvoon Sähköverkko faced several operational challenges:
Difficulty locating faults accurately, especially during storm events
Prolonged outage times due to time-consuming fault identification
Increased impact of coastal weather conditions on infrastructure
Need for faster and more efficient field response
Traditional methods lacked the precision required to quickly identify exact fault locations.
Safegrid’s Intelligent Grid System® was deployed to provide real-time monitoring and accurate fault localization.
Precise fault location detection
Real-time insights into grid conditions
Consistent performance during extreme weather
During a storm, a transformer pole snapped, causing:
An initial earth fault
Followed by a short circuit fault
Safegrid successfully located the fault with approximately 70-meter accuracy, enabling rapid response from field crews.
The Safegrid solution delivered significant advantages:
Consistent and accurate fault location
Faster identification of fault sites
Reduced reliance on manual fault tracing
Improved efficiency of maintenance operations
Enhanced resilience against weather-related disruptions
With Safegrid’s Intelligent Grid System®, Porvoon Sähköverkko achieved:
Consistently accurate fault localization
Fault location accuracy within ~70 meters
Reduced outage durations and faster restoration
Improved operational efficiency during storms
“The Safegrid system has located grid faults consistently over time with good accuracy. This has helped us to find and fix faults faster.”
— Mikael Hämäläinen, Operations Manager
Porvoon Sähköverkko’s experience demonstrates the importance of accurate fault detection in maintaining reliable power distribution, especially in coastal regions prone to extreme weather. By adopting Safegrid’s Intelligent Grid System®, the utility has significantly improved its ability to locate faults quickly and respond efficiently.
This case highlights how precise, real-time monitoring can reduce downtime, lower operational costs, and ensure consistent service delivery in even the most demanding environments.
