A high-voltage lead-through device includes an insulator body having a solid exterior and including insulation, a main conductor passing therethrough, a sensor adjacent the main conductor inside the insulator body measuring a physical property of the device and a communication unit adjacent the main conductor outside the insulator body, wherein the main conductor has a first electric potential, a section of the solid exterior of the insulator body faces a second electric potential, the communication unit is connected to the sensor using a signal conductor as a first electrical communication medium and the communication unit employs a different communication medium for communicating with a data distribution device at a third electric potential.

A wound electrical component includes a wound body comprising a plurality of wound layers of an electrically insulating material around a longitudinal axis of the body. The component also includes at least one printed electronics sensor consisting of printed circuits on a flexible substrate. Each sensor is interleaved between two of the wound layers of the wound body.

A device including a corona shield, and at least one support element for connecting the corona shield to a high voltage apparatus. The at least one support element includes a semiconducting polymer, which, when in operation, acts as a resistance between the corona shield and the high voltage apparatus. Furthermore the support element is arranged to fix the corona shield to the high voltage apparatus.
