SYNOPSIS

A new IEEE C57.104-2019 Guide or the Interpretation of Gases Generated in Mineral Oil-Immersed Transformers was released last year. The IEE working group has completely revised the IEEE guide and a new method for rate of change of gas has been developed. This webinar will discuss the changes in the IEEE C57.104-2019 and how rate of gas formation is calculated for offline DGA. Rate of gas formation helps to investigate if the issue in the transformer is – transient, intermittent or continuous.

Changes in rate of gas formation can also indicate deterioration or stabilization of the fault. This is where online DGA becomes advantageous, the webinar will also introduce when online DGA should be considered by users.
