A review of electrostatic monitoring technology: The state of the art and future research directions

Abstract

Electrostatic monitoring technology is a useful tool for monitoring and detecting component faults and degradation, which is necessary for system health management. It encompasses three key research areas: sensor technology; signal detection, processing and feature extraction; and verification experimentation. It has received considerable recent attention for condition monitoring due to its ability to provide warning information and non-obstructive measurements on-line. A number of papers in recent years have covered specific aspects of the technology, including sensor design optimization, sensor characteristic analysis, signal de-noising and practical applications of the technology. This paper provides a review of the recent research and of the development of electrostatic monitoring technology, with a primary emphasis on its application for the aero-engine gas path. The paper also presents a summary of some of the current applications of electrostatic monitoring technology in other industries, before concluding with a brief discussion of the current research situation and possible future challenges and research gaps in this field. The aim of this paper is to promote further research into this promising technology by increasing awareness of both the potential benefits of the technology and the current research gaps.

Numerical analysis and experimental verification of the induced waveform characteristics for aeroengine gas path debris electrostatic sensor

“…14 In 2010, Chinese researchers have also carried out some monitoring experiments and successfully monitored the occurrence of failures. [15][16][17][18][19][20][21] Due to the advantages of electrostatic monitoring, it has been applied to F-35 Joint Strike Fighter. 7 In 2017, Powrie et al reviewed the development of electrostatic monitoring for decades.…”

Electrostatic sensors – Their principles and applications

“…Condition monitoring of mechanical wear is essential to assess the health status of mechanical components and systems. Compared to conventional techniques based on vibration monitoring and temperature detection for condition monitoring of mechanical wear and associated prognostics, the electrostatic sensing technique offers a better or complementary means to provide timely warning of developing faults [92]. In this case electrostatic sensors detect charged debris resulting from the wear of mechanical parts or systems.…”

Research on Electrostatic Monitoring of Tribo-Contacts with Dynamic Adaptive Fusion Method

“…Necessary actions can be taken with scheduled maintenance to avoid the failure of mechanical equipment with successful condition monitoring techniques [4][5][6][7]. Nowadays, a unique developing technique that is called the electrostatic monitoring method has been investigated based on electrostatic charging phenomena [8,9].…”
