Combined transformer for intensity and voltage, with open ferromagnetic nucleus for tension (Machine-translation by Google Translate, not legally binding)

摘要

Combined transformer for current and voltage with open ferromagnetic core for voltage, characterized in that the voltage transformer has an open core constituted by a bar and connected to earth, whose insulation at the end of the voltage terminal is covered by a conductive layer of the electricity and that the current transformer has an annular primary winding, housed inside an insulating enclosure connected externally to the ground, while the conductors contain, on the one hand, the shaft of the current transformer and, on the other hand, the transformer The tension, have conical shapes directed in opposite directions, such that the sum of the outside diameter of the shaft and the voltage transformer is approximately constant, at least along the entire axial section of the wound part of the voltage transformer.
