  • Protective device and system
    Patent number: 6628494
    Abstract: A multi-pole protective device and system for electrical power transmission and distribution systems is provided that operates a multi-pole tripping system at ground level from a line-potential tripping device contained within each pole of the multi-pole system. The system includes multiple pole-unit assemblies each of which is totally self-contained and generates a tripping signal in response to overcurrent conditions to operate a ground-potential operating mechanism. In one arrangement, the pole units each include an internal line-potential tripping arrangement that communicates a trip signal to a ground-potential operating mechanism of the pole unit and associated pole units of the protective device arrangement. In a preferred arrangement, the line-potential tripping arrangement includes an insulated member that is moved to transmit the trip signal from line potential to ground potential.

  • Method and arrangement for minimizing electrical field stress in circuit interrupters and housings therefor
    Patent number: 6423903
    Abstract: A method and arrangement is provided for minimizing electrical field stress on circuit interrupters and their housings via the arrangement of the external sheds or skirts of the housing. In one arrangement, some of the sheds are grouped about each side of the open gap that is defined by the contacts of the circuit interrupter in an open position.

  • Protective device and system
    Publication number: 20020021540
    Abstract: A multi-pole protective device and system for electrical power transmission and distribution systems is provided that operates a multi-pole tripping system at ground level from a line-potential tripping device contained within each pole of the multi-pole system. The system includes multiple pole-unit assemblies each of which is responsive to sensed overcurrents to provide a tripping signal. Each of the pole-unit assemblies is totally self-contained and generates a tripping signal in response to overcurrent conditions to operate a ground-potential operating mechanism. In one arrangement, the pole units each include an internal line-potential tripping arrangement that communicates a trip signal to a ground-potential operating mechanism of the pole unit and associated pole units of the protective device arrangement. Each pole unit also includes an interrupter operated by the ground-potential operating mechanism to open the interrupter.
