Abstract
A sensor for permitting a signal carried on a tested conductor to be either inductive or capacitively coupled, in non intrusive manner, onto first or second output conductors includes a partially hollow material with high magnetic permeability wound by a first output conductor for permitting a signal carried on a tested conductor to be inductively coupled onto the first output conductor and a conductive material inserted partially within the hollow material and connected to the second output conductor for permitting a signal carried on a tested conductor to be capacitively coupled onto the second output conductor.
Claims4
A sensor for permitting a signal carried on a tested conductor to be either inductively or capacitively coupled, in non-intrusive manner, onto first or second output conductors, said sensor comprising:
- an at least partially hollow material having high magnetic permeability wound by a first output conductor, said partially hollow material permitting a signal carried on a tested conductor to be inductively coupled onto said first output conductor;
- and
- a conductive material inserted at least partially within said partially hollow material and connected to a second output conductor, said conductive material permitting a signal carried on a tested conductor to be capacitively coupled onto said second output conductor.
