ROGOWSKI COIL

摘要

PURPOSE: To provide a Rogowski coil which is hardly affected by fluctuations in temperature and made almost completely symmetrical with respect to an axial direction at relatively low cost. CONSTITUTION: This Rogowski coil is provided with at least a print wiring circuit card 1, equipped with a cut part of circular shape. This coil is manufactured of straight metallic deposits 3 on each of the two faces of a plate which is arranged as a radial part with the center of the cut part on its extension, and the electrical connection of the radial part on the one face with the radial part on the opposite face is conducted by a metal-coated hole 4 through the thickness of the plate.
