Abstract
A fuse housing assembly is disclosed that includes a rate release plug that prevents the emission of large quantities of dielectric oil from a transformer tank upon removal of a fuse holder from a bayonet-type fuse holder. The rate release plug allows pressurized gas inside the tank to escape while at the same time, impeding the flow of dielectric oil out of the tank.
