CAPACITOR ASSEMBLY

Capacitor assembly (1) for a voltage divider for sensing an elevated voltage in a MV/HV power distribution network of a national grid. The capacitor assembly comprises a body (100) comprising a solidified, electrically insulating casting material (90) and an integrated primary capacitor (40), operable in a high-voltage portion of the voltage divider, comprising a low-voltage electrode (80) and an elongated high-voltage electrode (20).The low-voltage electrode (80) is embedded in the casting material (90) and comprises a circumferential wall (50) forming an elongated cavity (30). The high-voltage electrode (20) is embedded in the casting material (90) and protrudes into the cavity (30). A portion of the casting material (90) is arranged in the cavity (30) between the low-voltage electrode (80) and the high-voltage electrode (20) such as to be operable as a dielectric of the primary capacitor (40).The circumferential wall (50) comprises a mesh of conductive wires (190) forming a plurality of apertures (60) between the conductive wires to allow the casting material (90) outside the circumferential wall (50) to be mechanically connected with the casting material (90) in the cavity (30) while the casting material solidifies and thereafter.
