Abstract

The disclosure relates to a sensored insulation plug (2) for insertion into the rear cavity of a medium or high-voltage separable connector in a national grid power distribution network. It insulates a connection element on elevated voltage and senses the elevated voltage. The insulation plug features a rotationally symmetric body (140) made of electrically insulating material (610). It includes an integrated sensing capacitor (150) functioning as a high-voltage capacitor in a sensing voltage divider, with a high-voltage electrode (160), in use connected to the connection element, and a sensing electrode (170) embedded in the insulating material (610). The dielectric of the sensing capacitor is formed by a portion (180) of the insulating material (610). The insulation plug also has a circuit board (206) with a signal contact (360) connected to the sensing electrode (170).The sensored insulation plug (2) includes a temperature sensor (500) on the circuit board, with a sensor probe (510) that senses the temperature in its vicinity, either in surface contact with or thermally coupled to the insulating material (610), to measure its temperature.
