FEATURED PUBLIC RELEASE

Delta-X Research announced the full release of its innovative technology called Reliability-based Dissolved Gas Analysis, a new method for interpreting dissolved gas analysis test data.

This new method for interpreting dissolved gas analysis data helps high-voltage equipment experts identify and assess power transformer abnormalities by correlating fault gas production with transformer failures, the company said in a press release.

Unlike conventional dissolved gas analysis which uses a simple limits-based approach, reliability-based DGA applies a statistical model built from real-world transformer reliability data, including failure events.

Reliability-based DGA has been added to Transformer Oil Analyst (TOA4), which is used by over half of the largest utilities in the USA and Canada, according to the company. All TOA4 subscribers can now conduct valuable comparisons between conventional DGA and reliability-based DGA on their own transformer fleets.

"Early results from this type of comparison show remarkable results," reports Delta-X Research President & CEO John Brett. "One of our customers, a major US utility, asked us to run a comparison of their entire 7,000+ transformer fleet with reliability-based DGA versus conventional DGA. In this case, reliability-based DGA uncovered nearly 1,000 transformers showing abnormalities that were not revealed by conventional DGA, while at the same time reducing the number of false alarms substantially."

"The utility has incorporated reliability-based DGA as a regular part of their transformer health surveillance process. We anticipate seeing this outcome from many of our customers as they employ Reliability-based DGA," Mr. Brett added.
