Reply to "TVS and Fast Acting Circuit Breaker help"

RWDeanoOGR Forum Member DIGITAL SUBSCRIBER

Follow up to my Question #2, scenario, a "Derailment" causes a fault (short circuit) , Circuit Breaker Trips, clear fault, clear short circuit (Derailment), reset circuit breaker, breaker trips repeatedly. Go to Track Block TVS where derailment has occurred, disconnect one TVS lead or both check continuity of TVS, with continuity TVS has collapsed "Shorted"and performed its function, replace TVS as it only has "one time" life function. Correct ?

So theoretically a "New" TVS would read open no continuity ? With out a scope is there a way to check that a "New" TVS is going to function, as we all know "QC" maybe a real variable.
