Grounding design analysis
Aydıner, Mustafa Güçlü; Özay, Nevzat; Department of Electrical and Electronics Engineering (2009)
This thesis investigates problematic cases in AC substation grounding system design. Particularly, the grounding design for substations that are built on high resistivity soil is considered. Here, possible physical rectification schemes are introduced and compared for their effectiveness from safety and cost efficiency perspectives. For this comparison, the CYMGRD program (a finite element analysis tool for AC substation grounding) is used for detailed analysis of the various schemes. An additional computer...
Ground Calibration of Antenna Arrays For Complex Platforms
Elbir, Ahmet M.; Tuncer, Temel Engin (2013-10-18)
When antenna arrays are placed on platforms, antenna patterns and antenna characteristics change significantly. Calibration of antenna arrays becomes an inevitable and important task to correct the imperfections due to the antenna surroundings. In this paper, a time-gating method is proposed to calibrate the direction finding antenna array on a UH-60 helicopter on ground. The helicopter is placed above the ground plane whereas the source antenna is further away to account for the reflections from the helico...
Ground-state properties of quasi-one-dimensional electron systems within dynamic local-field correction: Quantum Singwi-Tosi-Land-Sjolander theory
Tanatar, B; Bulutay, C (1999-06-15)
Dynamic local-field correction (LFC) brings a richer picture about the description of a many-body system than the standard mean-held theories. Here we investigate the ground-state properties of a quasi-one-dimensional electronic system using the quantum version of the Singwi-Tosi-Land-Sjolander (STLS) theory and present a critical account of its performance. The results are markedly different than those theories based on static LFC and the random-phase approximation; an example is the static structure facto...
