It might be possible that the Gen or turbine is not expanding axially properly. Check on the turbine side, guide rails  to see if the turbine is misaligned on the guiderail. Check if the expansion displacemnt probes are setup correctly and recording the expansion. check if your Steam control valve are synchronizing properly and distrubuting the steam evenly.

 

Expansion of the train is away from the generator towards the turbine

I haven’t used it but just based on a web search of several sites and reading the list of features it doesn’t seem appropriate for O&G except for perhaps some limited use.  What are your machine types? 

 

…the MicroLab can test all types of lubricants from engine oils to fluids for hydraulics, transmissions, power steering, gearboxes and generators.

 

…is a complete analytical system that delivers comprehensive test results for machine lubricants, including engine and gear box oils, hydraulic, power steering and transmission fluids.

 

…is the ideal tool for condition-based monitoring of high-use, reciprocating engines like high-mileage fleet trucks or heavy equipment used on location in industries like mining, maritime, and construction.

OSA4 is an excellent system.

Easy to be used, and having ready oil analysis software database system.

 

From my observation, OSA4 usually used by mining company, Heavy duty equipment contractor company which business is in mining sector, where engine oil analysis are dominant.

But for oil&gas / petrochemical, you will analyzing TAN more than TBN.

 

I prefer (for your case) to let the regular/routine oil analysis done by QA / Laboratory department, using the approved and dedicated ASTM instrument, which available in your plant facility.

 

For immediate analysis, you can purchase handy oil analysis instrument like Fluidscan Q1000, and Spectrovisc Q3000.
