First, the transformer has a large volume of oil as a fuel source. Second, the atmosphere is the source for oxygen. And third, the ignition source which is created by an internal arc from the faulted bushing completes the fire triangle.

volume of gas builds up, the pressure inside the tank increases significantly. As the metal tank starts to expand, it will deform and may even rupture. The consequences of such an explosion can include oil spills and even extensive fire damage to both the transformer and surrounding equipment.
