Abstract
A sensored insulation plug for a separable connector in a MV/HV power distribution network of a national grid, operable to sense the MV/HV elevated voltage. The sensored insulation plug includes a plug body formed by a solidified insulating material, a contact piece, and a discrete coupling capacitor embedded in the insulating material and operable to harvest energy from the elevated voltage of the contact piece and optionally operable to superimpose a communication voltage signal over the elevated voltage. The sensored insulation plug further includes an integrated sensing capacitor, operable as a high-voltage capacitor in a sensing voltage divider for sensing the elevated voltage. The sensing capacitor comprises a high-voltage electrode comprising the coupling electrode and the contact piece, a tubular sensing electrode, and a dielectric comprising a portion of the insulating material.
