Default Current transformer 250A

Hey folks ,

After the above, complete with burden characteristics . 250/25 or 10 would be ideal, thank you , will pay ! Needs to stand-off 7Kv although I can improve insulation if already reasonable. Will need to be effective at high frequency , 350Khz approx .


If no supply , I’m happy to have a go at building one from a suitable ferrite core under advice!

Anyone with anything would also need to know the frequency range

Let’s say a range between 220-330Khz
