xDGA is a free and open-source tool. xDGA implements a set of Excel formulas that give you the ability to run industry best-practice algorithms to evaluate and assess the results of Dissolved Gas Analysis in Liquid Filled Electrical Apparatuses such as Power Transformers, On-Load Tap Changers, Circuit Breakers, etc.
The custom formulas are packaged as an Excel XLL Add-in which doesn’t require any additional software installed on your computer. Simply double-click on the xDGA.ADDIN.xll file and start using the formulas.
If you’ve ever tried to apply any of the available analysis guidelines, you’ll know that some of them are dozens of pages worth of information. Wouldn’t it be nice if all those rules were condensed in easy-to-use formulas that can be applied to your existing DGA data? Well, xDGA does exaclty that.
Convert DGA Data
Use cells with DGA data and transform them into a standard format ready for consumption by the diagnosis algorithms.
Use the library of custom Excel formulas to run industry best-practice algorithms to diagnose the condition of each transformer.
Comprehensive Analysis Results
Dozens of pages worth of analysis, rules and criteria condensed in clearly organised outputs for each algorithm.
For a more detailed explanation of how to use this library you can check our “How to use xDGA” article.
