Glare evaluation of exterior lighting systems
Rampák, Dominik ; Baxant, Petr (oponent) ; Škoda, Jan (vedoucí práce)
Glare is an important, but often overlooked parameter in lighting systems design. This parameter can significantly affect human biorhythm, causing a discomfort or in the worst cases it can dazzle drivers, which can lead to car accidents. Therefore, it´s necessary for lighting designers to consider glare in their designs, specifically threshold increment value. This thesis focuses on glare measurement caused by exterior lighting systems and comparison of usage different types of camera lens for threshold increment measurements with luminance analyser. For a better understanding of the whole issue, there is a part describing how human eye perceives light, which is followed by definition and division of the glare. Afterwards, there is part describing calculation procedure of the threshold increment, which serves as a basis for the practical part of the thesis. Practical part of the thesis is dedicated to experimental measurement of glare from exterior lighting system on Technická street, right behind VUT FEKT T12 building. The measurement is done using luminance analyser and the LumiDISP program, while 3 lenses are used for the measurements. The output of this thesis are values of threshold increment obtained by using 4 different methods (3 lenses) and subsequent comparison of the suitability of the lenses for the glare measurements. To supplement, a simulation of the measured lighting system in the Relux program and a subsequent comparison of the results with the measured values are performed.

Utilization of SINCAL tool in the field of network protection
Rampák, Dominik ; Wasserbauer, Vojtěch (oponent) ; Topolánek, David (vedoucí práce)
This bachelor thesis is describing the basics of using program PSS SINCAL for protection of distribution networks. The thesis is divided into 3 parts. The first part is describing basics and functions of the program. The second part is devoted to the moduls, work with moduls described in form of manuals. The last part is describing creation of test network and simulation of single-phase to ground short-circuit to verify selectivity of the protection devices.
