My customer used Rogowski coil to sense the current with changing frequency on the fly. They found out the reading goes head-wired when frequency increase. They follow the set up procedure for the integrator. And they also notice there are degradation based on the ADE7880 datasheet. So is there any frequency limit (maximum freq) for the integrator to be used?
Attached the reading for your reference. kindly please help to advise.
Thanks and regards,
