Abstract
A magnetic core for a non-contact clamp-on current sensor having a magnetic core that is adapted for encircling a current-carrying conductor wherein the magnetic core includes a first portion having a first integral toroidal section and a first pair of opposing side walls extending therefrom, a second portion having a second integral toroidal section and a second pair of opposing side walls extending therefrom such that the first portion and second portion are coupled together at the first and second pairs of opposing side walls so to define an aperture therebetween for receiving a current carrying conductor and measuring the line current therein. The first and second integral toroidal sections of the magnetic core are designed so to be void of any discontinuities within the flow path of the magnetic flux and so to have a circular shape which promotes a more thorough flux saturation. The lack of discontinuities in, and the circular shape of, the flow path of the magnetic flux in the toroidal sections promotes a more thorough saturation of the magnetic core which results in the reduction of zero errors and the obtaining of more accurate line current measurements.
