A Review on Electrostatic Monitoring

This paper reviews the technique of electrostatic monitoring. Over the past twenty years, the technique of electrostatic monitoring has been developed and applied to aircraft and engine condition monitoring in a wide range of components. The first successful application was to gas turbine engines where it was used to detect the presence of foreign debris in the gas path. Subsequent research has shown that electrostatic sensing can be a powerful non-contact technique to monitor a range of tribological contacts. The processes in the study of the technique are presented, which gives a bright outlook of its future prospects.
