UK Power Networks identified the need to apply a systematic approach to interpreting results of transformer Dissolved Gas Analysis (DGA). This project provides an online tool to calculate a Health Index score for major transformers, tapchanger selectors, reactors and auxiliary transformers based on new and historic test results.
The project will investigate the following objectives:

  • Using DGA results to calculate a Health Index Score for Major Transformers and associated plant

  • Analysing trends in results over a 10 year period to calculate score.
