An arrester bypass device can include a switch having an normal state and an operated state. The arrester bypass device can also include a first electrode mechanically coupled to the switch, where the first electrode is held when the switch is in the normal state and released when the switch is in the operated state. The arrester bypass device can also include a second electrode positioned in line with the first electrode, wherein the first electrode contacts the second electrode when the switch is in the operated state. The arrester bypass device can further include a ground strap having a first end and a second end, where the first end is mechanically coupled to the plunger, and where the second end is mechanically coupled to an electrical ground.

Arrester bypass devices

An arrester for preventing an insulator supporting a power line from experiencing an electrical flashover comprises an electrode, a varistor, and a separating device. The electrode is spaced apart from the power line or a conductor that is electrically tied to the power line so as to define an external gap therebetween. The separating device, in turn, comprises two portions operative to separate from one another when the varistor experiences an electrical condition sufficient to cause the varistor to fail. The electrode, the external gap, the separating device, and the varistor are arranged in electrical series with one another and in electrical parallel with the insulator.

Externally gapped line arrester

A housing encapsulating first and second terminals of a surge arrester disconnector becomes structurally weakened before activation of a disconnect device in the disconnector when the disconnector is exposed to heat, thereby preventing the disconnector from producing a projectile with a force sufficient to classify the disconnector as a hazardous material under Department of Transportation regulations.

Fire safe arrester isolator

Retainers for movable surge arrester disconnectors to prevent relative displacement of the disconnectors with respect to the arrester within predetermined limits.

An electrical apparatus of an electric distribution power system includes an electrical device having a high voltage electrical terminal that may be energized, an exterior insulating housing, and an insulator. The exterior insulating housing surrounds and insulates the electrical device, and includes an opening through which the high voltage electrical terminal protrudes such that at least a portion of the high voltage electrical terminal is external to the exterior insulating housing. The insulator covers the electrical terminal and is attached to the exterior insulating housing such that no current flow path is provided through an interface between the insulator and the exterior insulating housing.
