ADE9153A Negative Data

Category: Hardware
Product Number: ADE9153A

Hello,

I am using the ADE9153A on a project to meter device connected to regular US wall outlets. It is designed similar to the eval board. Our product goes thru dielectric testing with a HP-2000S Hipot tester, at 840V DC for 2 seconds. Some of our units report occasional dips into the negative, is it possible that the ADE9153a could be damaged by dielectric testing given that the limit 240V?
