Abstract
Methods are provided for in-situ detection of varnish and/or deposit precursors in a lubricant in a lubricating environment. An electrostatic accumulator can be used within a lubricating environment to enhance accumulation of varnish and/or deposit precursors on portions of the electrostatic accumulator. The deposits accumulated on the electrostatic accumulator can then be characterized in-situ. The potential difference across portions of the electrostatic accumulator can cause an enhanced rate of deposit accumulation on the electrostatic accumulator, which can facilitate characterization of the tendency of a lubricant to accumulate deposits in the lubricating environment.
