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.

Advanced Moisture Assessment for Transformers

Moisture assessment is a complex topic for when it comes to high-voltage transformers. It’s difficult to interpret the water content of oil or paper insulation by looking at individual dissolved water measurements or time-series data, and increases in water solubility due to aging of oil make it risky to rely on relative saturation calculated from dissolved-water measurements based on the assumption that the oil is like new.
 
Check out this article by Dr. Oleg Roizman of Intellpower and our own Dr. Jim Dukarm to find out how a thermodynamic approach to assessment of water in transformers can solve these problems.
