PV Defects Identification through a Synergistic Set of Non-Destructive Testing (NDT) Techniques [PDF]
Sensors, 2023 A synergistic set of NDT techniques, including I–V analysis, UVF imaging, IR thermography, and EL imaging, supports a diagnostics methodology developed in this work to qualitatively and quantitatively identify a wide range of PV defects. The methodology is based on (a) the deviation of the module electrical parameters at STC from their nominal values ...

Ultrasonic Non-Destructive Testing (NDT) Using Wireless Sensor Networks
Procedia Computer Science, 2012 AbstractThis paper describes the integration of an ultrasonic-based non-destructive testing (NDT) with wireless sensor networks (WSNs) to continuously monitor material integrity during run-time. NDT is a technique that allows the examination of material properties without causing any damage to the material in the process.

Procedia CIRP, 2015 AbstractA tier 1 automotive supplier has developed a novel and unique kinetic energy recovery storage system for both retro-fitting and OEM application for public transport systems where periodic stop start behaviour is paramount. A major component of the system is a composite flywheel spinning at up to 36,000rpm (600Hz).

Terahertz based non-destructive testing (NDT) [PDF]
tm - Technisches Messen, 2020 Abstract Established methods based on X-rays, ultrasound, thermography, eddy current, and optics are very effective in fault detection and structural analysis. However, these methods are limited for some applications, for example, the non-destructive testing of fiber-reinforced plastics, foams, and sandwich or hollow structures. In these

Advances in applications of non-destructive testing (NDT): a review
International research journal of engineering, IT & scientific research, 2021 Manufacturing defects and discontinuities in a product are anomalies which can lead to severe damages which may sometimes involve loss of life. These defects must be examined and corrected before the product goes into service. There are two methods of testing a product for defects and discontinuities viz. Destructive Testing and Non-Destructive Testing.

Digital NDT (Non Destructive Testing)
IFAC Proceedings Volumes, 1995 Abstract The objective of this work was to improve the electronics of an NDT(disperse magnetic flux) equipment by means of real time digital processing of the signals coming from the field, thus increasing reliability, precision, accuracy and decreasing calibration times. An electronic defect simulator was built in order to obtain signals similar to
