Abstract
A sensor for use in detecting a time-varying current in a conductor (106) comprises plural sets of two oppositely-configured sensor elements (104-1 . . . 104-6) arranged around a sensing volume having a central axis, the sensor elements (104-1A, 104-1B) of each set being provided substantially in a common plane that does not intersect the central axis, and each set having a different common plane, the sensor elements of each set being arranged such that a normal (N) of their common plane at a point between central parts of sensor elements lies on a plane (P) that is radial to the central axis of the sensing volume.
