Abstract: The invention relates to a current sensor comprising an electric conductor (10), through which a first current (I) can flow parallel to a first direction (R1) and which comprises three regions (21, 22, 23) immediately following on from each other in the first direction (R1). A middle region (22) of the three regions (21, 22, 23) comprises a conductor cross-sectional area that is smaller than a conductor cross-sectional area of each of the two outer regions (21, 23) of the three regions (21, 22, 23). A voltage sensor of the current sensor is designed to measure a first voltage between the two terminals (41, 42) thereof. The first voltage is the same as a voltage applied to a measuring region (22, 25) at least partially coinciding with the middle region (22).

Abstract: A method for checking an electrical current measurement includes a first step of measuring a current to be measured IM using a current measuring structure. The method also includes a second step of superimposing a test current IP on the current to be measured IM to form a resultant current IRes=IM+IP. The resultant current IRes is measured in a third step using the current measuring structure within a period of time of the second step. In a fourth step, a check follows in order to determine whether the resultant current IRes measured in the third step corresponds to a sum of the current IM measured in the first step plus a known magnitude of the test current IP superimposed in the second step.
