Applicaton Notes
User Notice
1) The Rogowski coil can measure any primary current as there is no saturation effect.
2) Not tested given that in the worst case (load = 0 Ohm i.e. short circuit on the output) the peak dissipated power remains low (< 2 Watts)
3) Frequency bandwidth and phase shift modelling schematic can be provided on request.
4) Referring to the main phase offset of 90 ° (a Rogowski coil is a derivative current transducer)
5) Considering a primary conductor of at least ⌀ 15 mm, perpendicular and in contact with the Rogowski coil.
6) Considering an external conductor of at least ⌀ 15 mm the same current level than internal conductor, perpendicular and in contact with the Rogowski coil.
