Abstract: Bushing for connecting a separable connector to a switchgear or to a transformer in a national grid for distributing electrical power at medium or high voltages. The bushing comprises a) a bushing body of a solidified, electrically insulating casting material; b) a bushing conductor, embedded in the casting material, for conducting power at medium or high voltages into the switchgear or the transformer, and c) an integrated primary capacitor, operable in a high-voltage portion of a voltage divider for sensing a voltage of the bushing conductor. The primary capacitor comprises a low-voltage electrode, a high-voltage electrode and a dielectric. The high-voltage electrode is a section of the bushing conductor. The low-voltage electrode is embedded in the casting material and comprises a circumferential wall surrounding the bushing conductor and forming a cavity. The dielectric is formed by a portion of the casting material arranged in the cavity. The circumferential wall comprises a mesh of conductive wires forming a plurality of apertures between the conductive wires to allow the casting material radially outside the circumferential wall to be mechanically connected with the casting material in the cavity.

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. A dielectric formed by a portion (180) of the insulating material (610) is arranged between the sensing electrode (170) and the high-voltage electrode (160).
