Can partial discharge testing on live medium voltage cable cause the cable to fail?
 
Not if you are using the cable's own voltage and capacitive couplers. Or any technique where you do not use an external voltage.
I am just starting to learn how to use PD tests, so my answer is probably not covering all aspects.
