UCC28600: Circuit Diagram to build a 3 phase 8KV Protection circuit Using UCC28600DR (28600D)

Hi,

Thank you for the query on UCC28600.

I could not see any reference designs which which have tested for 8kv surge. You might want to check the guidelines and standards which apply to your system and select the components accordingly. Below are few references which might help.
