Turbine Lubricant Testing

The importance of oxidation-resistant turbine oils in the various applications in which turbines are used are difficult to understate. Turbines in themselves are very costly energy-converting mechanisms which, among other applications, provide much of the electricity for the power grids of modern society. Most critical to these turbines are the lubricants that are essential to their operation in long, dependable service. Equally critical, then, are the tests that determine the acceptability of these turbine oils and the understanding of the oxidation mechanisms that cause these oils to form deposits and otherwise lose their ability to properly lubricate the turbine. Savant Labs offer test methods for turbine lubricants including viscosity, oxidation resistance, and wear testing, including General Electric GEK32568H Turbine Oils Specification.
