Abstract: A device to measure the voltage at a test point, also referred to as a test point voltage sensor, comprises a housing formed from a first material and a second material, wherein the first material comprises an insulating material and the second material comprises a conductive or semiconductive material. The housing includes an opening configured to cover a test point of a cable accessory. The device further includes a pressure pad, disposed in the housing, having a conductive mating surface configured to contact a test point of the basic insulation plug or end plug. The device further includes a low side capacitor embedded in the housing and electrically coupled to the conductive mating surface. The device further includes a signal wire electrically coupled to the low side capacitor.
