Application and performance Pressure release valves play a vital role in the protection of oilimmersed electrical equipments, such as transformers, high voltage switch gears, capacitor and on load tapchangers, etc. This device can prevent the oilimmersed electrical equipment from deformation or rupture. Should a fault occur in such electrical equipment, from deformation of rupture? Should a fault occurring in such electrical equipment, they are instantaneously vaporize the oil causing extremely rapid buildup of gaseous pre
