Abstract
A device for measuring the intensity of an electric current which has a simple and economical design and offers a high measurement dynamic compatible with combined measurement, protection and energy metering applications. The device () is insensitive to parasitic fields and to the position of the electric conductor to be measured, and that can be opened to facilitate placement thereof. The device () defines a closed path (C), about a conductor () for the circulation of the lines of magnetic field induced by the current to be measured, and the path is formed by two plates () having a high magnetic permeability separated by two air gaps (E) closed by two identical and opposed electric coils () for supplying a voltage proportional to the derivative of the intensity (I) of the current to be measured. The device () reduces the is compact so that it can be easily integrated into any type of electric appliance.
