Definitions

  • the present invention relates to a construction system for a voltage and/or current sensor.
  • the object of the present invention is to overcome the aforementioned drawbacks.
  • the invention which is characterized by the claims, resolves the problem of creating a construction system for a current and/or voltage sensor intended for use in combination with a busbar, in which said construction system extends along its longitudinal axis, thus forming a proximal and a distal portion with respect to said busbar, in which said construction system comprises a body formed from insulating material, a source electrode extending longitudinally along its longitudinal axis and having a proximal end connected to said busbar and a free distal end, a first screening element intended to form a screened chamber, and a first electrical field sensor placed in said screened chamber and spaced axially apart from the free end of said source electrode, and in which said construction system is characterized in that a second capacitive sensor, intended to detect the electrical field generated by said source electrode, is placed in the proximity of a proximal axial portion of said source electrode.
  • this shows a first embodiment of the construction system proposed by the present invention, in which said construction system 100 relates to a voltage sensor intended for use in combination with a busbar B, in which said construction system 100 extends longitudinally along its longitudinal axis Y-100, thus forming a proximal end 101 and a distal end 102 with respect to said busbar B.
