CURRENT PROBE Russian patent published in 2007 - IPC G01R15/00 

FIELD: the invention refers to electrical measuring technique and designed for using in circuits of measuring devices of calculation of alternate current and of registration of electric power.

SUBSTANCE: the given result is achieved due to changing of configuration of the current bus and this allows distribute more evenly the power lines of the magnetic field. The proposed current probe has a current bus and two inductance coils installed on the circuit board and having two windings, the first of which is the measuring one, and the second winding coiled round the first one, serves as electrostatic screen. At that the current bus is fulfilled in the shape of a loop consisting of a closed and an open turns embracing correspondingly the first and the second inductance coils.

EFFECT: increases accuracy of measuring the current.
