A line protection system described herein provides reliable electro-mechanical connections between system components, reduces mechanical stresses on a disconnector, assures more effective disconnection of a failed arrestor, and is lower in cost than existing systems. The line protection system includes a surge arrestor, a disconnector coupled to the surge arrestor, and a line lead coupled to the disconnector. The line lead generally is a high strength cable and/or the line protection system generally does not include a shunt bypass assembly. Upon exposure to a high voltage condition, the disconnector actuates and separates the line lead from the system.

Line protection systems

A device includes a cover that includes a base. The cover is configured to be positioned over a mount that couples a support structure of an electrical device to another element. The electrical device includes an energized terminal that is configured to connect to an electrical power system and a grounded terminal. The device also includes an insulating interface coupled to the base of the cover such that, when the cover is positioned over the mount, the interface contacts the support structure to substantially electrically insulate the mount. A system includes an electrical device, a support structure that holds the electrical device on the first side, a mount configured to couple the structure to another element, the mount being grounded during operation of the system, and a protective device positioned over the mount.

Protective device

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

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.
