Transformer Field of influence
Transformer Field of influence
(OP)
Hello there.
I am using cats resin type transformers (5kv primary - 208Y/120v secondary) and am looking for tables or graph that would show the emi sphere of influence from a distance "x" from transformers for a kVA size. I have looked at a few transformer manufacturers and they do not seem to have that information.
Thanks.

For what do you need to know a level of emi? Properly electromagnetic field is concentrated in transformer core. There is a directive of electromagnetic compatibility for electric and electronic devices and installation rules which manufacturers recommend to use when you arrange an equipment.

I have called several transformer manufacturers and it does not appear that this information is available.
