Helping you keep the power on and the world moving forward.
We are Delta-X Research.
Discover decision-support tools that elevate your transformer maintenance program so you can
manage risk with confidence.
Scientific
We challenge the status quo by applying the scientific method and building on first principles. We invest in research to provide high quality information so you can make high quality decisions.
Easy
Quality information presented simply and conveniently makes critical decision-making easier. And knowing the team behind the information is always available to assist provides confidence in making those hard choices.
Independent
Leading with science demands objectivity. And by providing decision-support tools without associated services or hardware, we can work with any other vendor. By us being independent, you are independent.

Utilities, heavy industry and service companies have relied on Delta-X Research since 1992.
15 of the top 20 US utilities are Delta-X Research customers.
Meet Delta-X Research
Delta-X Research provides the market-leading solution for managing and interpreting insulating liquid test data, including dissolved gas analysis (DGA). Our Transformer Oil Analyst™ (TOA™) decision-support tool uses innovative Reliability-based DGA to detect incipient faults, assess risk, and prioritize your transformer fleet for repair-or-replace decisions.
What is Reliability-based Dissolved Gas Analysis (R-DGA)?
Dissolved gas analysis is one of the most widely used diagnostic tools for detecting and assessing changes to the condition of a liquid-filled transformer, and IEEE and IEC standards provide detailed procedures for interpreting dissolved gases in power transformers.
But there is still a significant number of unplanned outages due to transformer main tank faults that, in retrospect, should be detectable by DGA and maintenance teams are frustrated by pursuing an unreasonable number of false alarms raised by conventional DGA.
You can improve system reliability and avoid false alarms by using Reliability-based DGA, an improved method for interpreting DGA data that associates fault gas production with transformer failures and provides a direct indication of risk that is actionable.
