<p>A dry-type network transformer has a core and coil windings insulated by a combustion-inhibiting gas. The combustion-inhibiting gas, core and coil windings are disposed within a hermetically-sealed enclosure. The combustion-inhibiting gas is air, an inert gas or a mixture of gases. The dry-type network transformer may be connected to a network protector. The network protector is further connected to a secondary network. The network protector prevents power from flowing from a secondary network to the primary side of the transformer. The dry-type network transformer is installed in a vault that is underground or at ground level. The dry- type network transformer may be suspended near the ceiling of the vault or installed at the base of the vault.</p> |
