here are the few plots for further discussion.
hintn 25-07-19 morning 6:52AM there was a sudden drop in RPM from 10500 to 10000RPM with in a min span RPM reached to 10500RPM during same time orbit seperated.upto 3days occassionally observed seperated orbit same time 0.5X peak observed
Hi, can you share more detail please, also if you share the filtered orbit also please share the unfiltered, i cannot seen your purpose on sharing 1x filtered orbit alone.
Why there is a sudden drop of RPM? have you gone in any testing? or your running steady state operation then the RPM sudden change? any problem in line frequency?
How many bearing do you have? 4 bearing? if 4, can you share to use the data of Bearing 2,3,4 = Turbine DE, Gen DE an NDE.
Also whats the point in sharing polar plot and SCL plot during steady state?
When you share a data to someone else for review please give as much a right details.
