A tool for reliability and safety: predict and prevent equipment failures with thermography

Recursive construction of output-context fuzzy systems for the condition monitoring of electrical hotspots based on infrared thermography

“…(II) Predictive maintenance: Predictive maintenance refers to the maintenance of electrical equipment on the basis of the direct monitoring of actual operating conditions and the regular collection of data on measurements, efficiency, heat distribution, and other indicators instead of depending on statistical or historical data. A predictive maintenance program schedules all maintenance activities according to factual data and repairs the equipment if necessary before the occurrence of failure (Epperly et al, 1997).…”

Recent progress in diagnosing the reliability of electrical equipment by using infrared thermography

“…Faults in electrical power systems can be classified into a few categories, such as poor electrical connections, short or open circuits, overloads, loads imbalance and improper equipments installation [1,3,5,[8][9][10]. In most cases, poor electrical connections are among the common problems in transmission and distribution lines of electrical power systems [4].…”

“…It is recommended that for an extensive outdoor inspection, especially during sunny periods, long-wave (generally 8-14 lm) sensing of IRT systems will give superior results. This is because in this wave band, the thermal detectors have greater sensitivity to ambient temperature objects and have good transmission through smoke [3,8]. Short-wave systems should be used only on a limited basis, or if loads and other conditions allow, on overcast days or at night [6].…”

Thermal Imaging for Enhancing Inspection Reliability: Detection and Characterization

“…It is recommended that for an extensive outdoor inspection, especially during sunny periods, long-wave (generally 8 µm -14 µm) sensing of IRT systems should be used. It had been proven that within this wave band, the thermal detectors provide greater sensitivity to ambient temperature objects and insensitive to atmospheric attenuation (Balaras & Argiriou, 2002), (Epperly et al, 1997). Short-wave systems should be used only on a limited basis depend on the condition of loads and time (Hellier, 2001).…”
