Hydrogen gas is found in transformer oil as a byproduct of the decomposition of the oil due to electrical or thermal stress, such as arcing, overheating, or partial discharges within the transformer. When the oil breaks down, it releases various gases, with hydrogen being one of the most common, particularly in the early stages of fault conditions.
