Abstract
The paper describes the DC characterization of AC current shunts recently developed at the Faculty of electrical engineering and computing, University of Zagreb (UNIZG-FER). The shunts of cage type design include nine shunts that range from 1 mA up to 10 A. The following DC properties were inspected: long time drift, temperature coefficients and power coefficients. The results have shown that shunts have low temperature (<7 µΩ/Ω/°C), and power coefficients (<10 µΩ/Ω/W), and small drift which makes them suitable for precise power measurement applications. Also, relative humidity dependence of currents shunts is investigated.
