Turbine Oil Analysis -Monitoring Program (TOA-M) Turbine Oil Analysis-Quality and Performance Program (TOA-QP) Oil Sampling Sampling Location Sampling Frequency Sampling Quantity Oil Analysis Report Turaround Service Time Example of Oil Analysis Report The in-service monitoring of gas and steam turbine oils has long been recognized by the power generation industry as being necessary to ensure long trouble-free operation of turbines (according to ASTM D-4378-08). FocusLab has extensively experienced and technically full advanced testing program for predictive and proactive turbine maintenance program Focuslab has developed Turbine Oil Analysis Package , Testing and Program . They are divided and grouped into 2 categories:- 1.Turbine Oil Analysis -Monitoring TOA-M 2.Turbine Oil Analysis -Quality and Performance TOA-QP

1.Turbine Oil Analysis -Monitoring (TOA-M)

Modeled from the tests recommendation in ASTM D 4378-08 for regular monthly
oil analysis-monitoring in order to monitor wear metal debris , oil consition .
and contamination.

2.Turbine Oil Analysis -Quality and Performance (TOA-QP)

Modeled from the tests recommendation in ASTM D 4378-08 for additional tests in
quarterly , semi-annually and annually in order to know oil quality and performance.
Tests in TOA-QP are as following:-

• RPVOT or RBOT
• FTIR
• Foaming Characteristic
• Air Release
• Water Separability ( water - oil separability or Demulsibility)
• Rust Preventives
• Copper Corrosion
  

Recommendation as Turbine Oil Analysis- Quality and Performance -TOA-QP

Modeled from the recommendation in ASTM D-4378-08 for quarterly , semi-annual
and annual sampling interval for the first 12 month operation and normal operation

Oil Sampling

Ideally and technically, the good oil sample should be the most representative of the
body of lubrication system and have lowest contamination to the oil information .
Or simply , the good oil sampling will have to meet 2 objectives as following :-

• Maximize data Density of oil information
• Minimize disturbance

The oil should be sampling while turbine is running and reached its operating temperature
If unable to take sample while turbine is runing ,then it should be done as soon as
possible after the turbine engine has stopped.
The oil should be sampling,preferably while the oil is in turbulent flow point or
free-flowing line, not a dead zone line or location.

Sampling Location

It is essential to establish suitable and correct sampling points on the turbine lube system..
to be monitored , such that consistent samples can be taken as easily as possible.

Turbine Lube System Sampling Points should be designed to have both primary sampling
points and secondary sampling points

• Primary Sampling Point

Location where regular routine oil samples are taken for monitoring and trending
wear metal debris ,oil condition and oil contamination .
See picture T1

• Secondary Sampling Point

For dianostic and trouble shooting
For measuring wear metal debris and oil contamination by individual components , and
can be located anywhere on the system to isolate upstream components. This is
where wear metal debris and contamination contributed by individual components will
be found.
See picture T1

Sample Quantity

Turbine Oil Analysis -Monitoring (TOA-M)
Both TurbineCheck 813 and TurbineCheck 814 of TOA-M Program will require
approx 100 ml .

Turbine Oil Analysis -Quality and Performance (TOA-QP)
TOA-QP Program may require approx 700-1000 ml for each sample ,
depend upon to test parameters.

Oil Analysis Reports

TurbineCheck™ Oil Analysis Report feature :- Display an easy-to-read and understand. Information for wear condition ,lubricant condition and contamination. Interpretation and recommendation of the result . Option for Bilingual. Color coded display of overall condition for present sample and history condition of previous sample.

Color coded problem highlights. Provide new oil or reference oil for comparing result and as baseline. Publish Alarm Limit range of the equipment and oil. Comprehensive trending graph of most parameters. TurbineCheck™ Oil Analysis offers reporting options via internet, email and fax.

Turnaround Service Time

Turbine Oil Analysis -Monitoring ( TOA-M)
The report is typical available within 2-3 working days of sample receipt at FocusLab's labortory.
(For the first time of delivery new unit equipment sample , it may take approx 5 working days.)

Turbine Oil Analysis -Quality and Performance (TOA-QP)
Most the test in Turbine Oil Analysis-QP will take 7-10 working days
