KNOWLEDGE IS PROFIT! LEARN HOW TO LOWER YOUR LOST
PRODUCTION FACTOR
The rotor of a wind turbine generator (WTG) will easily top 200 million revolutions in 20 years.
Wear is enormous. Not least to the gearbox where numerous particles are released from the components to the oil. But if you monitor the size and number of these particles, you can forecast serious problems, optimise operation and schedule maintenance well in advance.
With the data provided by OCM 30X, you will not only get the earliest possible warnings of gearbox failures and component-specific problems. You will also get an in-depth understanding of gearbox wear under different operation conditions. This will help you improve operation, maintenance as well as rootcause analysis dramatically. In short, OCM 30X will not only protect your investment. It will increase your ROI.
SMALL PARTICLES ARE THE WORST It is critical to monitor the occurrence of small particles the size of 4 to 21 microns.
Their size and number reveal gearbox wear under different operating conditions, and thus the need for maintenance and changes in operation. When particles above the size of 100 microns appear, it is often too late to take simple preventative action.
The degradation of the component’s surfaces is highly advanced. However, the OCM 30X is the market’s only device that offers exact monitoring of contamination from particles as small as 4, 6, 14 and 21 microns.
One option is to employ the CJC™ Oil Contamination Monitor.
The OCM 30X monitors particle contamination as small as 4 microns in the air-containing oils of a WtG gearbox. You can collect all data from OCM 30X remotely and analyse them using either
cjconline.dk or your company’s SCADA- system.
PROFIT FROM INCREASED ROI With remote monitoring and sample response intervals as short as 20 seconds, you can collect data under all operating conditions, even when the WTG is inaccessible for physical inspection.
Figure 1. Shows how OCM 30X measures the size and number of particles in WTG gearbox oil under different operating conditions. The graph also shows how OCM 30X monitors abnormal particle peaks that reveal wear problems indicating a future breakdown.

DOES NOT CONFUSE AIR BUBBLES FOR PARTICLES the oil in a WtG gearbox is whipped full of air. But unlike other measuring methods, OCM 30X is not air sensitive. It measures the light’s refraction to monitor all kinds of particles exactly; soft and solid, magnetic as well as non-magnetic.
It completely ignores air bubbles, which makes it the market’s most accurate monitoring method for this purpose.
PREDICT AND PREVENT GEARBOX FAILURE
If you take a look at Figure 1, you will see how OCM 30X monitors the number and size of particles under different operation conditions. The graph is a readout from a 2 MW WtG.
The number of particles peak when operation conditions change, such as filter replacement and cooling problems. The read-out from OCM 30X also reveals abnormal particle peaks that can’t be explained by changes in operation. these peaks should be analysed carefully to assess degradation of components and prevent breakdowns.
ONLINE ANALYSIS
In this specific case, all data was analysed using
cjconline.dk, and the customer was warned well in advance about an impending breakdown. preventive maintenance was scheduled, and the physical inspection confirmed the readouts from oCM 30X and the analysis using
cjconline.dk.
Components were changed in time, and the customer prevented an extremely expensive breakdown.
