Abstract: A device for gripping a cable is presented that has a retention member rotatably disposed within a cable guide such that upon entrance of the cable within an entrance port, the cable moves between the retention member and a wall, causing the retention member to simultaneously rotate and move toward the exit port and away from the wall until it abuts the exit wall and rotates in place as the cable is pushed out the exit port. When the cable is pulled toward the entrance port, the retention member simultaneously rotates and moves toward the entrance port and the wall, wedging the cable between the wall and the retention member.

The spring may be located between a portion of the first member and the washer. The torsion spring may be located between the washer and the nut, where the torsion spring causes the nut to rotate when force is applied to an upper part of the first member.

Abstract: A hotstick operable electrical connector for use in a power distribution system that includes a housing, a well and first and second frustoconical members extending from a surface of the housing. Each frustoconical member has a distal end and an axial bore that extends from the distal end into the housing.

An electrical contact assembly extends through the aperture between the cavity and the axial bore. The integrally formed well provides a means for direct connection with an insert device without the use of an adapter.

Abstract: A method for identifying a fault condition associated with a power line conductor of an electrical power distribution network. The method determines if a load current carried by the conductor is above a minimum load current, determines a learned phase angle relationship between the load current and a source signal, determines a load current magnitude, determines a real-time phase angle relationship between the load current and the source signal and indicates a fault condition when the real-time phase angle relationship is within a predetermined number of angular degrees of the learned phase angle relationship and when the load current magnitude exceeds a fault-indicating current.
