Non-Intrusive Fault Detection in Reciprocating Compressors [PDF]

open access: yes, 2012
This research presents techniques developed for non-intrusive sensing and fault detection in reciprocating compressors driven by induction motors. These procedures are “non-intrusive” because they rely only on voltage and current signals measured on the ...

Two Stage Helical Gearbox Fault Detection and Diagnosis based on Continuous Wavelet Transformation of Time Synchronous Averaged Vibration Signals [PDF]

open access: yes, 2012
Vibration signals from a gearbox are usually very noisy which makes it difficult to find reliable symptoms of a fault in a multistage gearbox. This paper explores the use of time synchronous average (TSA) to suppress the noise and Continue Wavelet ...

Integrated fault detection and supervisory compensation for hydronic radiator faults in district-heated buildings

open access: yesResults in Engineering
Hydronic radiator faults in district-heated buildings can degrade comfort, alter return-water temperatures, and increase unnecessary heat use. Although many fault detection and diagnostics studies identify anomalies, fewer close the loop by translating ...

Decoding pixels: A modular software prototype for cognitive image-based diagnostics of PV plants

open access: yesEPJ Photovoltaics
Although aerial infrared (aIRT) imagery-based solutions for diagnostics of PV plants demonstrate impressive time-efficiency and spatial resolution, they also suffer from considerable drawbacks: limited automation (hence, expert dependence) and ...
