Rogowski Coil....

Any oldtimers here ever designed a Rogowski Coil using PC board techniques?

I am trying to find some examples and tips. This is not for commercial use,I just want one for myself for testing.

Thanks.....(Nice site BTW)

I've never heard of it before.
According to Wikipedia, it looks like a kind of current transformer.

I found this pdf on those coils. https://www.electro-tech-online.com/custompdfs/2008/08/Pr9.pdf
The file came from this site. **broken link removed**
