What is the analysis of gas in oil for transformers?

The analysis of gas in oil for transformers, often referred to as Dissolved Gas Analysis (DGA), is a critical diagnostic tool used to assess the condition of transformer oil. This analysis detects and quantifies gases dissolved in the oil, which can indicate potential faults such as overheating, arcing, or insulation breakdown. By monitoring these gases, operators can predict failures and implement maintenance strategies to enhance transformer reliability and longevity.
