Hmmm...Don't know about "completely": see my images just posted, "5" vs. "5A".

Hi Ken,
I have a 1000:1 current shunt I guess used for high power 60Hz meters.

I can assure you that they are completely worthless at say 100kHz+
frequencies. I think the metal in them has very poor skin depth or
something. But they report very high voltages at high frequencies...
Current transformers are the way to go for sure!!
Cheers,
Terry
the 100 mV/50 A shunt.......
