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

An electrical assembly having an elongated electrical component, such as a surge arrester, coupled to a grading device for distributing an electric field along the electrical component as a continuous operating voltage is applied to the electrical component. The grading device includes a grading body that is coupled to the electrical component. The grading body includes semi-conductive materials. The semi-conductive materials can be nonmetallic. The grading device has improved flashover resistance over conventional metal grading devices.

Grading devices for a high voltage apparatus

A communications interface accessory for an electric power system arrester is described. The communications interface accessory includes a housing and a communications interface positioned within the housing. The communications interface is configured to complete a signal path with the arrestor. The communications interface accessory also includes a disconnect device positioned within the housing, whereby the disconnect device is coupled to the arrestor and the communications interface.

Communications interface accessory for power system arrester

In one embodiment, a system for coupling communications signals onto a medium-voltage power line includes a metal oxide varistor, a disconnect device and a capacitor. The metal oxide varistor is electrically coupled to the medium voltage power line. The disconnect device includes a resistor in parallel with an air gap and is electrically coupled in series between the metal oxide varistor and a communications device. The capacitor is electrically coupled to the metal oxide varistor and the communications device in parallel with the disconnect device.
