Design and Modelling of a Shunt for Current Measurements at 10 a and up to 1 MHz: A Theoretical Approach

Résumé

Electrical current shunts used as resistance standards in metrology laboratories are characterized by a broadband operating frequency bandwidth and are commonly calibrated up to 100 kHz. The use of a current shunt requires the preliminary knowledge of its magnitude deviation from DC and phase angle according to the frequency. The best magnitude performances published so far are limited to \pmb2 μΩ/Ω at 100 kHz. In this paper, we present an innovative shunt design for current measurements at 10 A up to 1 MHz. The relative deviation from DC is less than \pmb0.2 μΩ/Ω and \pmb20 μΩ/Ω in magnitude at 100 kHz and 1 MHz respectively.
