Abstract

Sensored insulation plug (1) for being inserted into a rear cavity of a medium-voltage or high-voltage separable connector in a power distribution network of a national grid. The sensored insulation plug comprises a) a plug body (140) formed by a solidified insulating material (610), and b) a primary capacitor (150), operable as a high-voltage capacitor in a voltage divider for sensing the elevated voltage, the primary capacitor having i) a high-voltage electrode (160) for direct electrical connection to the elevated voltage; ii) a sensing electrode (170) of a tubular shape, embedded in the plug body (140), arranged around the high-voltage electrode, and comprising a 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; iii) a dielectric formed by a portion (180) of the insulating material (610) arranged between the sensing electrode (170) and the high-voltage electrode (160). The mesh is a deformable mesh, adapted to be deformed by insulating material in liquid state flowing around the mesh before solidification of the insulating material.
