Hey all!  Recently noticed an elevated radial vibration above 6 mils and also 4 times the amount of H2 leak occurring in a 200+mw generator.  I'm unable to get a spectrum and have not much to go on and thought I would ask for some ideas on trouble shooting.  

1. can grid instability cause rotor eccentricity and stress the h2 seals?

2. could a shaft rub cause a seal damage and result in both hydrogen leakage increase as well as elevated vibration? (I assume so)

3. Could delamination or any type of stator vibration cause these symptoms?  (If I can magically get a spectrum pulled I should be able to tell pretty quickly if theres a rub event, however I doubt they have a VM600, imx or system 1 to get that data.  



Thanks for any insight!

Best,

Paul
