Hi everyone,

I am pulsing a Rogowski coil. I have been reading a lot about these coils, and maybe I am missing something very simple, but I don't have a good understanding of why there is droop (tilt) in my current pulse waveform, and how to calculate it as a percentage to compare with the datasheet specifications.

Any help is appreciated, thanks!

 

Would you like a wild guess?
For a better answer, post your schematic and any other info about the coil.

 

My question is more general. I don't understand why there is a current droop.

I am using a Rogowski Current Transducer CWTUM/1/B/1/80. In its data sheet, there is a brief explanation and calculation of droop. I don't understand what the phase displacement is or where it comes from and how it distorts the waveform.
