Best Practices in Dissolved Gases Analysis (DGA) for Power Transformers (Noviembre 2014)

Abstract

Over the years it has been shown Dissolved Gases Analysis technique for power transformers has become a powerful tool for diagnosing the state and condition, as well as equipment failures, with the advantage that it is possible to do with the transformer in normal operation. This document presents some collected practices of professional exercise to improve the entire process of Dissolved Gases Analysis, from sampling to the diagnostic for power transformers.
