What Rogowski Coil Is
Air core di / dt sensors measuring alternating currents in primary induces a secondary voltage in the coil that is proportional to the rate of current change.
Rogowski coils have an associated phase shift of 90 degrees at all input frequency. This phase shift of Rogowski coils can be compensated by minus 90 degree phase shift using the integrator.
