What is the purpose of DGA for transformer oil?

The purpose of DGA for transformer oil, which stands for Dissolved Gas Analysis, is to monitor the condition of transformer oil and assess the health of transformers by analyzing the gases dissolved in the oil. By detecting specific gases that are produced by insulation breakdown, overheating, or arcing within the transformer, DGA helps identify potential faults early, allowing for timely maintenance and preventing catastrophic failures. It serves as a vital predictive maintenance tool, supporting the longevity and reliability of transformer systems while ensuring optimal performance.
