SUMMARY When a fault arc occurs in oil-filled electric equipment, it generates a flammable gas and a dynamic pressure rise. In this study, the pressure rises due to the arc are measured in a closed vessel containing air and oil for different arc dept
Alternative test method of internal arcing for replacing SF6 by air in SF6-insulated power equipment
