Continuous wavelet transform for ferroresonance phenomena in electric power systems
Akıncı, Tahir Çetin; Ekren, Nazmi; Şeker, Serhat; Yıldırım, Sezen (Elsevier Sci Ltd, 2013)The common characteristics of a nonlinear system are multiple equilibrium points, limit cycles, jump resonance and sub-harmonic generation. Ferroresonance is also a nonlinear electrical phenomenon, which occurs frequently ... -
Detection of Ferroresonance Phenomenon for the west Anatolian Electric Power Network in Turkey
Akıncı, Tahir Çetin; Ekren, Nazmi (2011)Ferroresonance is an electrical phenomenon in nonlinear character, which frequently occurs in power systems containing saturable transformers and single or more phase switching on the lines for the disjunction of the loads. ... -

Energy saving in lighting system with fuzzy logic controller which uses light-pipe and dimmable ballast
Görgülü, Sertaç; Ekren, Nazmi (Elsevier Science Sa, 2013)Approximately, 20% of the electricity consumed in the world is spent for lighting. More efficient utilization of the sun, as a natural source of light, for lighting would save electricity used for lighting. The aim of this ... -
Examination of Harmonics in Incandescent Lamps and CFLs
Aykut, Ercan; Dursun, Bahtiyar; Büyüktümtürk, Fuat; Ekren, Nazmi (London Science Publishing Ltd, 2010)Compact fluorescent lamps (CFL) are widely used in lighting technology since they have less power consumption and more efficiency compared with incandescent lamps. They require neither external ballast nor a starter. ... -
An investigation into the usability of straight light-pipes in Istanbul
Ekren, Nazmi; Görgülü, Sertaç (Sila Science, 2012)With the impact of global warming, recent years has witnessed a tremendous revival of interest in environmental issues. At the moment, the world's electricity generation mainly depends on the fossil fuels which are eventually ... -
