Based on real-world data and first principles of science, Transformer Oil Analyst (TOA) is a risk assessment and key decision support tool designed to assess the state of high-voltage apparatus and help you make decisions regarding the maintenance, refurbishment, and replacement of critical assets with confidence, while optimizing capital budgets, maintenance of and capital planning for equipment like power transformers. 

TOA is enhanced with an innovative method called Reliability-based DGA. Rather than using the simple limits of setpoints of conventional DGA, Reliability-based DGA identifies and assesses power transformer failure data. By tracking the fault energy index related to dissolved gases, Reliability-based DGA is able to assess the transformer gassing behaviour to detect a fault, identify the type of fault, and indicate the severity, all while outperforming conventional DGA.
