Hi,

I must protect my device. To do it i have used isolated DC/DC power source, and two ADuM1310. Problems occur when i should connect TVS to ground . I dont know which place is better, or im  not sure in 100%. Isolated ground or field ground. I think better is field ground because electrical disturbance have shorter path to ground compared to isolated ground. I will appreciate any help. Sorry for my english.
