Abstract

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.
