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.

The price of an oil transformer varies widely based on factors such as size, capacity, voltage rating, and the specific application. Prices can range from a few thousand dollars for smaller transformers to several hundred thousand dollars or more for large industrial-grade transformers. For accurate pricing, it’s best to consult with manufacturers or suppliers directly.
