Aurtra Transformer Monitoring Technology

Logo

Aurtra addresses the lack of visibility of transformer insulation health and the impact of operating conditions on transformer life.  The technology is built on a foundation of over 10 years of research at the University of Queensland in close co-operation with a number of the largest Australian power networks using decades of transformer data.


Aurtra’s solution provides IoT monitoring of water in oil, temperature, vibration, acoustic and RF noise and online automated health analysis.  With a simple installation and automated communications, the Aurtra Insight dashboard offers a fleet-wide view of transformer insulation condition, including estimated life left given current operating conditions, temperature, water content, DP assessment and forecast, partial discharge and vibration trends. 
 
  • Track operating state and trends mapped against safe limits
  • Forecast end-of-life based on the insulation aging rate with current loading and moisture levels
  • Detect maintenance problems remotely with early warning of leakages and cooling system problems
  • Determine the optimum conditions for maximum asset utilisation over life with sophisticated scenario tools that model the impact of changing loads and cooling configurations.

Solution Architecture

Robust, secure solution architecture
Compliant with international data security standards, the Aurtra IoT sensors communicate using 3G/4G networks to the Aurtra cloud.  Aurtra’s cloud-based proprietary algorithms automatically analyze the remote sensor data.  Users log in to the web-based Aurtra Insight dashboard to view fleet-wide analysis.  For users with existing Asset Management systems, the Aurtra solution architecture can deliver interoperable, single sign-on access to both data services and complex Aurtra asset condition vizualisations.

Secure, open API
All data, including raw measured and derived data is available using Aurtra’s secure API, for integration with corporate ERM, CNAIM, historian and other business support systems.

IoT Data Security
Aurtra has designed the IoT data transfer processes, storage, access and management operations to all be compliant with EU Utility critical infrastructure data security requirements.




Data Logger Hardware Guarantee
Aurtra provides a life-long replacement warranty and upgrade guarantee with ongoing subscriptions to our  service.
