The dry-type network transformer may be connected to a network protector.

It is not submerged and therefore the system is protected from floating debris.

The dry-type network transformer is installed in a vault that is underground or at ground level.

In a non-submerged mode, too, the zero-depth pressure as a reference is measured and stored in predetermined time intervals.

The pump assembly has a pump motor (100) with a non-submersed aluminum winding (110) terminating in and secured to at least one non- aluminum metallic electrical connector (140) about a non-submersed interface.

The dry- type network transformer may be suspended near the ceiling of the vault or installed at the base of the vault.

A dry-type network transformer has a core and coil windings insulated by a combustion-inhibiting gas.
