• Cloud-Based Software Delivers Real-Time Insights
• The innovative system offers instant access to critical performance data via the cloud, enabling seamless monitoring and improved maintenance planning. Benefits include enhanced reliability, extended component lifespan, early fault detection, and optimized condition-based maintenance strategies.

Streamlining Inspections with ABB’s Digital Technology

Helsinki University Hospital transitioned to ABB’s cloud-based monitoring system in under an hour, eliminating the need for labor-intensive physical transformer inspections.

Jari-Pekka Korhonen, Operations Manager at the hospital, shares: “We manage both dry and oil transformers, requiring regular monitoring. Previously, inspecting oil transformers necessitated a full shutdown to collect samples—a significant challenge in a hospital conducting 87,000 surgeries annually, with numerous patients relying on life-support systems.”

Korhonen adds, “Our facility spans a vast area, and my team cannot be everywhere at once. Remote monitoring was essential.”

Introducing ABB Ability™ Asset Manager for Transformers

In collaboration with Danish startup Oktogrid, ABB developed the ABB Ability™ Asset Manager for Transformers, enabling the hospital to monitor transformer performance and trends remotely and in real time. This solution has drastically reduced physical inspections and costly shutdowns, while offering hospital management actionable insights on transformer efficiency and performance.

The system is compatible with any transformer—regardless of type, manufacturer, or age—leveraging sensors to measure sound, vibration, temperature, and magnetic fields. This ensures real-time monitoring without asset downtime.

Helsinki University Hospital: A Critical Healthcare Provider

As Finland’s largest healthcare provider, Helsinki University Hospital (HUS) serves 2.2 million residents across 24 municipalities. Treating 700,000 patients annually and employing 27,500 professionals, HUS consumes energy comparable to a small town. Reliable power supply is critical to maintaining 100% uptime in this life-saving environment.

“We now receive uninterrupted, real-time transformer data, which wasn’t possible through visual inspections alone,” Korhonen explains. “Previously, inspections could only identify obvious issues like leaks or temperature changes. Now, we monitor transformers 24/7 and address problems immediately.”

Expert Insights from ABB

Sixten Holm, Business Development Manager at ABB Electrification Service, comments: “We’re thrilled to assist HUS in overcoming inspection challenges. Our transformer sensing technology has minimized the need for physical inspections and oil analysis, while providing vital data for early fault detection and condition-based maintenance.”

Holm continues, “Many transformers in use today go decades without monitoring due to high costs and complexity. The ABB Ability™ Asset Manager for Transformers offers a simple, cost-effective solution for modernizing electrical grids.”
