SENSORED INSULATION PLUG WITH TEMPERATURE SENSOR

Abstract

A sensored insulation plug for insertion into the rear cavity of a medium or high-voltage separable connector in a national grid power distribution network. The sensored insulation plug insulates a connection element on elevated voltage and senses the elevated voltage. The insulation plug features a rotationally symmetric body made of electrically insulating material. The sensored insulation plug includes an integrated sensing capacitor functioning as a high-voltage capacitor in a sensing voltage divider, with a high-voltage electrode, in use connected to the connection element, and a sensing electrode embedded in the insulating material. The dielectric of the sensing capacitor is formed by a portion of the insulating material. The insulation plug also has a circuit board with a signal contact connected to the sensing electrode and further includes a temperature sensor disposed on the circuit board.
