Re: current transformer

Yes you can buy current transofmers. Take a look at Digi-Key for example
Digi-Key

You can also design them yourself, if you want, just do a google search on "current transformer design" and you will get lots of hits.

Take a look at this https://leeh.ee.tut.fi/transformer/tra35.htm

Magnetics Corporation (makers of magnetic toroids and other materials) offers free software to design current transformers. You can download it here https://www.mag-inc.com/software/transformer.asp

I hope these resources help you out.

Cheers,
