Where To Collect A Sample
There are several components of a wind turbine that are critical to operation and those that will incur substantial costs due to unplanned maintenance and downtime and should be considered for testing.

Critical components include:Inside Wind Turbine

  • Turbine Gearbox
  • Main Shaft Bearing
  • Generator Bearings
  • Hydraulic Pitch System
  • Pitch Drive Gears
  • Pitch Bearings
  • Yaw Drive Gears
  • Yaw Bearings

Grease Analysis

Grease Analysis
Grease-lubricated bearings in wind turbines should be included in an effective condition monitoring program. At TestOil, we offer multi-faceted analysis to detect wear particles, contaminants and additives for in-service greases. Through routine sampling we are able to trend the data to identify potential problems before a major repair is required.

Wear metals are analyzed elementally via spectroscopic analysis to target the smaller, normal wear particles, and contrasted against Ferrous Wear Concentration which also detects larger, ferrous wear particles. Optionally, we may also perform Analytical Ferrography for determination of the wear mechanisms and severities of observable wear particles.

The additives are verified to ensure the correct grease is in use and not contaminated with another product. Contaminants, both particulate and water, are measured to determine when contaminants are increasing to a detrimental level.
