Detection and monitoring increased levels of electrostatic charge, produced as a result of machinery component deterioration, have the potential for the basis of an oil system component condition monitoring system. As increases in electrostatic charge level may be associated with the earliest stages of oil film/contact breakdown and the onset of wear, then charge monitoring may be used to identify a wide prognostic window over which component condition may be determined. The ability to monitor component deterioration from an early stage, and hence predict when replacement is required, will enable greater flexibility in terms of maintenance planning and equipment availability. This paper reviews the state of the art of using the electrostatic technology for monitoring component condition and deterioration, discusses the possible electrostatic charge generation mechanisms at the oil-component surface interface and the influence of oil chemistry under wear conditions. Results are included from simple tribometer and component rig tests.
