An Integrated, Multi-Method Software Platform for Advanced Dissolved Gas Analysis in Power Transformers

  • Unique Paper ID: 183613
  • PageNo: 2386-2394
  • Abstract:
  • Dissolved Gas Analysis (DGA) is universally recognized as the most effective non-intrusive method for monitoring the condition of oil-immersed power transformers, providing critical insights into incipient thermal and electrical stresses. However, the diagnostic reliability of DGA is often challenged by the limitations of individual interpretation techniques, which can yield ambiguous or conflicting results for the same dataset. This article presents a comprehensive, client-side software analyzer designed to mitigate these uncertainties by integrating a suite of established and novel graphical DGA methods into a single, interactive platform. The tool automates the complex plotting and interpretation of the complete Duval Triangle suite (DT1, DT4, DT5), the advanced Duval Pentagons (DP1, DP2), and the prognostic Low Energy Degradation Triangle (LEDT). By synthesizing results from these complementary methodologies and incorporating advanced trend analysis, the platform enhances diagnostic accuracy and provides asset managers with a holistic, data-rich view of transformer health, facilitating more reliable and informed maintenance decisions.
