The presence of hydrogen in transformer oil indicates potential internal issues, such as electrical discharges, arcing, or overheating. Hydrogen is one of the first gases to be produced when there is a fault in the transformer. Its detection through Dissolved Gas Analysis (DGA) can signal the need for further investigation to prevent possible transformer failure.
