Abstract
An electrical equipment is provided that prevents uncontrolled explosions that may occur due to arc faults in the tank. During an overpressure condition caused by an arc fault, the top of the tank ruptures along a weakened region. Cooling oil that escapes during a rupture is redirected by a deflector to prevent the oil from spraying outward from the tank.
