Bringing science to transformer risk management
Generation, transmission and distribution utilities, as well as leading industrial operations around the world, rely on Delta-X Research to provide accurate and timely insights into the health of their high-value assets. We provide advanced diagnostic software to assess and track the health of high-voltage electrical apparatus. Our solutions provide accurate and timely insights into equipment like power transformers, so our customers can increase reliability, optimize maintenance and maximize ROI, helping them to confidently safeguard assets and manage risk in an imperfect world.
Our flagship software, Transformer Oil Analyst™ (TOA) is the market leader for managing and interpreting insulating fluid test data for high-voltage apparatus. TOA has been used by utilities and heavy industry for over 20 years, and over half of the largest utilities in the USA are TOA subscribers.
TOA users now have access to an innovative new method called Reliability-based Dissolved Gas Analysis, the most correct interpretation of DGA available today. It applies an advanced statistical model based on real-world DGA results and associated failures to correctly detect and assess abnormalities in high-voltage transformers.
The Delta-X Research Difference
We are committed to helping the electric power industry improve the reliability and optimize the investment in high-voltage apparatus by:
- Investing in research to provide a sound scientific basis for interpreting test data for high-voltage apparatus.
- Applying our research to create the most effective diagnostic and condition assessment tools of their kind.
- Making significant contributions to the IEEE and other international standards for electrical equipment condition assessment by sharing our research results for general industry use.
- Providing open, secure and independent solutions so you and your enterprise systems have unfettered access to leverage your data 24/7.

Advancements in Dissolved Gas Analysis: Risk Assessment
In this short article from Electricity Today, Drs. Draper and Dukarm describe what modern statistics can say about transformer risk assessment, once steps have been taken to improve DGA interpretation (as outlined in previous articles).
Advancements in Dissolved Gas Analysis: Data Quality
Data quality is essential for effective dissolved gas analysis. Trend evaluation and accurate assessment of short-term changes require accuracy and low measurement variability of gas data – so data quality problems must be recognized and dealt with before any DGA interpretation is attempted. Learn more about common data quality issues in this short article from Electricity Today.
Advancements in Dissolved Gas Analysis: CO/CO2 Ratio
When conducting dissolved gas analysis, the detection of carbon oxide gases indicates a deterioration of paper insulation within the transformer. Find out more about how the ratio of these gasses can be used to help assess possible issues within the transformer in this short article from Electricity Today Magazine.
