Temperature Measurement of Photovoltaic Modules Using Non-Contact Infrared System
Jovanovic, Ugljesa,Mancic, Dragan,Jovanovic, Igor,Petrusic, Zoran The Korean Institute of Electrical Engineers 2017 Journal of Electrical Engineering & Technology Vol.12 No.2
This paper presents temperature measurement of solar photovoltaic modules using the custom-made system composed of an infrared temperature sensor and a microcontroller. The obtained measurement results are processed, displayed and stored on a PC using the custom-made virtual instrument. The proposed system overcomes some of the problems related to the contact sensor application, and at the same time offers accurate readings and better flexibility. The proposed system is especially suitable for applications where the cost is a limiting factor in the choice of measuring system. The conducted analysis and the obtained results have shown an excellent accuracy of the proposed system in comparison to a high quality thermal imaging camera used as the reference instrument.
[ ] System: Structural Study of the Influence of Luminescence Center Concentration
Rabanal M.E.,Gomez L.,Khalifa A.,Mancic L.,Milosevic O.,Torralba J.M. 한국분말야금학회 2006 한국분말야금학회 학술대회논문집 Vol.2006 No.1
The influence of doping on the structural and morphological properties of the phosphor system, obtained ultrasonically via Spray Pyrolysis from common gadolinium and europium nitrate solutions, was studied. The particle morphology, crystalline and chemical structure were studied by XRD, SEM and EDS. TEM was applied in order to identify the structure and growth of "primary nanoparticles" and determine the presence of domains locally affected by "Moires Frames" and "Crystallite Size". The SADP allows determining the presence of a polycrystalline material with two phases in the "as-prepared" samples, and only an Ia3 phase along the thermal treatment.
