The TVS is not like an MOV that degrades for each spike, they normally have a pretty long life. Also, the predominant failure mode is shorted, so the chances of having an open TVS aren't that great.

I agree with John.

To add to what John said, if you have inadequate over current protection (breaker) then the TVS will first short, but may open due to excessive current through the TVS. Fast breakers will should prevent a TVS from going open.
