Two fundamental differences arise between a traditional split-core current transformer and a Rogowski coil, even if both of them are current transducers:

  • the Rogowski coil is flexible and deformable, while a CT is rigid and non-deformable;
  •  considering the same primary current, the Rogowski coil occupies less space. For those reasons, the solution with Rogowski coils becomes profitable when an electrical panel upgrade is required and the available space is not large.
