Abstract
A Rogowski coil measures a current in a conductor and includes first and second loops electrically connected in series with each other. The first loop is wound with a substantially constant winding density in a first direction around a first core that has a substantially constant cross section. The second loop is wound with a substantially constant winding density in a second direction around a second core that has a substantially constant cross section. A direction of the first loop is substantially perpendicular to the normal of the first core cross section. Moreover, a direction of the second loop is substantially perpendicular to the normal of the second core cross section.
