The invention belongs to the field of devices and processes for measurement of electrical quantities and more precisely refers to measuring sensors and the procedures for measuring bus bar current with skin effect correction.The invention in the subject solves the problem of designing a measuring magnetic current sensor, the signal-primary current ratio of which is frequency independent in a relatively wide frequency range. This is achieved so that the invention in the subject explains the measuring procedures and the embodiments of the measuring sensor with skin effect correction in the bus bar as the following: with asymmetric positioning of the magnetic sensor with respect to the bus bar (1), reduction of lateral dimensions of the bus bar (1) in the vicinity of the magnetic sensor (2), and the implementation of a magnetic filter (4), the implementation of an open magnetic yoke (5), and the implementation of an electric filter (6) and the combination of two or more above mentioned methods.
