CURRENT SENSOR Russian patent published in 2007 - IPC G01R15/18 G01R19/15 

FIELD: the invention refers to electrical measuring technique.

SUBSTANCE: it is designed for using in measuring circuits of measuring devices of calculation of alternate current and registration of electric power. The technical result from realization of the given invention is in increasing accuracy of measuring current due to exclusion of additional temperature error. The proposed current sensor has two inductance coils winded round one frame installed on a circuit board and a current bus fulfilled in the shape of a U-shaped board. At that the inner part of the current bus has the first and the second apertures and the bus is bended in such a way that the first and the second apertures have a common geometric axle and embrace correspondingly the first and the second inductance coils installed vertically.

EFFECT: increases accuracy of measuring current.
