Electrical verification circuit for a current clamp, corresponding current clamp, and corresponding verification method

An electrical current-measurement verification circuit (100) for a current clamp (1), the current clamp configured to operate in a calibration mode or a clamp operation mode, the circuit (100) comprising:

• at least one electrical conductor (101) having at least one winding (101a) configured to be arranged around a jaw (11) of the current clamp, said at least one conductor (101) being configured to be electrically connected to a source of direct current so as to have a direct current of a predetermined intensity (I) flowing through itthe at least one electrical conductor (101), and
• a switch (105) electrically connected to said at least one conductor (101) andto switch in a verification mode after the calibration mode and before the clamp operation mode, the switch (105) configured to take at least:
• a position preventing the direct current from flowing in said at least one conductor (101) during the verification mode;
• and
• a position allowing the direct current to flow in said at least one conductor (101) during the verification mode, so as to verify whether the current clamp (1) is measuring an intensity value representative of the predetermined intensity (I) flowing through said at least one conductor (101) when the switch (105) is in the allowing position.
