Cause of the explosion when the power distribution box was switched on

A transformer explosion is caused by an internal short-circuit in the transformer. During short-circuit, oil temperature reaches 1200 degrees Celsius, and it gets vapored and evolves into explosive gas. These failures often cause loud. Electrical transformers are very powerful electrical devices and they take megawatts of electrical power and either step up or step down the voltage in order to make it safe for the electrical load attached to the transformer. During this conversion, a lot of stress is applied on the parts of the. Saw a squirrel touch the wrong part of a power line once, an arc and flame the size of a car exploded in the sky and the squirrel fell on the ground and instantly caught the brush around it on fire. It is one of the electrical power grid's most dangerous and disruptive events. Therefore, we need to ensure the reliable operation of the power transformer.
