  • Publication number: 20260079182
    Abstract: A sensored insulation plug for insertion into the rear cavity of a medium or high-voltage separable connector in a national grid power distribution network. The sensored insulation plug insulates a connection element on elevated voltage and senses the elevated voltage. The insulation plug features a rotationally symmetric body made of electrically insulating material. The sensored insulation plug includes an integrated sensing capacitor functioning as a high-voltage capacitor in a sensing voltage divider, with a high-voltage electrode, in use connected to the connection element, and a sensing electrode embedded in the insulating material. The dielectric of the sensing capacitor is formed by a portion of the insulating material. The insulation plug also has a circuit board with a signal contact connected to the sensing electrode and further includes a temperature sensor disposed on the circuit board.

  • Patent number: 12553921
    Abstract: Sensored insulation plug (1) for being inserted into a separable connector in a power distribution network comprises a plug body (140) formed by a solidified insulating material (610), and a primary capacitor (150), operable as a high-voltage capacitor in a voltage divider for sensing the elevated voltage. The primary capacitor includes a high-voltage electrode (160) for direct electrical connection to the elevated voltage. A sensing electrode (170) of a tubular shape, embedded in the plug body (140), arranged around the high-voltage electrode, comprises a deformable mesh of conductive wires forming a plurality of apertures between the wires to allow portions of the insulating material (610) on opposite sides of the mesh to be mechanically connected with each other by insulating material in the apertures while the insulating material solidifies and thereafter.
