Everyone says, "Probably a blown fuse," but what does that even mean and what causes it? Find out here. An electrical explosion is the sudden release of energy due to a short circuit between power phases or a phase to ground. When this happens, a transformer explosion may occur. When the power surge is too high, such as in lightning strikes, the incoming electrical line may carry enough electricity to start boiling the mineral oil (or the insulation fluid), effectively evaporating it or heating it past the fire point and increasing the pressure in the transformer.
