摘要： A condenser core for being positioned around a high voltage main electrical conductor, the condenser core including an electrically insulating body; a longitudinal through hole for accommodating the main electrical conductor; a plurality of electrically conductive foils encircling the through hole and being surrounded by the body such that each foil is insulated from any other of the foils; a potential electrical conductor for establishing an electrical connection between one of the foils and the main electrical conductor when the main electrical conductor is accommodated in the through hole; and a fastening device configured to mechanically connect the potential electrical conductor to the main electrical conductor when the main electrical conductor is accommodated in the through hole. A bushing, a high voltage application and a method of producing a bushing are also provided.

摘要： 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.

摘要： A flange fitted around a round cylindrical condenser core of a bushing is described. The flange comprises an annular lower flange part arranged to fit around a radial shoulder of the condenser core such that a lower shoulder chamfer of the shoulder rests against lower flange chamfer of the lower flange part around the circumference of the condenser core; and an annular upper flange part fastened to the lower flange part and fits around the condenser core above an upper shoulder chamfer of the shoulder. An upper flange chamfer of the upper flange part is between an upper sealing element and a lower sealing element, forming an annular chamfer space is formed between the upper flange chamfer and the upper shoulder chamfer between the upper and lower sealing elements. The flange comprises an injection through hole for a filler material to be injected there through to fill the chamfer space.
