Turbine Oil Testing Offered by Eurofins TestOil

Although turbine oil could last for more than a decade, it can start degrading long before that. Given this and because oil is the lifeblood of turbines, regular testing is important.

While monthly oil analysis delivers a basic view of the oil’s condition, there are additional tests that should be performed annually to monitor key performance characteristics of the oil and help prevent unexpected downtime. Critical indicators commonly uncovered in an analysis include a failing foam test, a failing demulsibility test, low RPVOT and high varnish potential.

                The recommended monthly test slate might include:

• Acid Number: This is useful in monitoring acid buildup in oils due to depletion of antioxidants.
• Spectroscopic Analysis:  This test measures the levels of specific chemical elements present in an oil. 

• Fourier Transform Infrared Spectroscopy (FTIR): This compares infrared spectra of used oil to a baseline spectrum.
• Viscosity: This test measures the oil’s resistance to flow and changes may indicate contamination or degradation.  
• Particle Count: Higher levels of particulates in the sample may indicate excessive particle ingression or filtration issues.
• Karl Fischer Water: Elevated levels of water contamination may indicate poor contamination control.  

In addition to these monthly tests, an Annual Turbine Analysis includes the following tests:

• Color: Sudden changes in color may indicate a problem.
• Demulsibility: This measures an oil’s ability to separate from water.  
• Foam: This test evaluates the sample ability to separate from air.
• Membrane Patch Colorimetry:  This measures the color bodies of insoluble contaminants in lubricants.
• Rotating Pressure Vessel Oxidation Test (RPVOT): This test measures the oil’s resistance to oxidation.  
• Remaining Useful Life Evaluation Routine (RULER): This measures hindered phenolic and aromatic amine antioxidant content.
• Rust: This measures the ability of industrial oil to prevent rusting under conditions of water contamination.

The resulting annual turbine analysis report is a complete rundown of each of the tests performed, along with a detailed explanation of each test result. The report will also contain a summary of findings, as well as recommended actions specified by Eurofins TestOil analysts.

                Ultimately, no turbine can perform optimally with degraded oil. With regular testing, that’s one issue plant managers can take off their plate.
