Insulating gas Working Principle laboratory

Working principle of Buchholz relay. Faults that occur inside an oil-filled transformer generates heat, much enough to decompose the insulating oil. In the case of large faults, a huge amount of gases are produced by the decomposition of oil. This results in an oil surge that moves towards the oil...
