Electrical Verification Circuit For A Current Clamp, Corresponding Current Clamp, And Corresponding Verification Method

Abstract: The invention relates to an electrical current-measurement verification circuit (100) for a DC current clamp (1), comprising: at least one electrical conductor (101) having at least one winding (101a) configured to be placed around a jaw (11) of the current clamp, said at least one conductor (101) being configured to be electrically connected to a DC power source so as to have a direct current of predetermined strength (I) pass therethrough, and a switch (105) electrically connected to said at least one conductor (101) and configured to adopt at least one position preventing the flow of current in said at least one conductor (101) and one position allowing the flow of current in said at least one conductor (101). The invention also relates to a current clamp incorporating such an electrical circuit (100). The invention also relates to a verification method using such an electrical circuit (100).
