Abstract Double‐loop Rogowski coils have become increasingly popular in the market because of their high sensitivity and flexible usage compared to their extended single‐loop coils. Due to the high number of turns (thousands) and its small turn diameter (<0.17 mm), it is very hard to draw 3D models of double‐loop coils with graphical software, let alone calculate electrical quantities by simulating them on the computer. To meet market's needs for designing high‐accuracy double‐loop coil, a method for calculating its low‐frequency coefficient of the double‐loop coil is presented. This calculation method is applicable to low‐frequency current‐carrying conductors of various geometric configurations. All experimental results verify the methods....
