Claims
- 1. A circuit-parameter sensing device comprising:
- a circuit conductor;
- current sensing means disposed about said circuit conductor; and
- an insulating support body of electrically insulating material incorporating said current sensing means and said circuit conductor, said circuit conductor having a first portion disposed through said current sensing means, said first portion having a section of narrowed cross section about which said current sensing means is disposed.
- 2. The circuit-parameter sensing device of claim 1 further comprising means for providing electrical connections between said current sensing means and an exterior portion of said insulating support body.
- 3. The circuit-parameter sensing device of claim 1 further comprising voltage-sensing means being disposed within said insulating support body.
- 4. The circuit-parameter sensing device of claim 3 further comprising means for providing electrical connection between each of said current sensing means and said voltage sensing means and an exterior portion of said insulating support body.
- 5. A circuit-parameter sensing device comprising:
- a circuit conductor;
- current sensing means disposed about said circuit conductor; and
- an insulating support body of electrically insulating material incorporating said current sensing means and said circuit conductor, said circuit conductor having a first portion disposed through said current sensing means, said first portion having a cross section that is narrowed compared to adjacent portions of said circuit conductor.
- 6. A circuit-parameter sensor comprising:
- an insulator body of electrically insulating material;
- a circuit conductor disposed through a portion of said insulator body;
- current sensing means disposed about said circuit conductor and within said insulator body; and
- means for providing electrical connection through said insulator body between said current sensing means and an exterior point of said insulator body, said circuit conductor having a first portion of narrowed cross section in the vicinity of said current sensing means.
