Electrical installation with intelligent lighting systém
Benčo, Tomáš ; Červinka, Dalibor (referee) ; Ondrejček, Vladimír (advisor)
The aim of this thesis is primarily to get acquainted with the possibilities of intelligent lighting solutions in buildings. The first part of this thesis consists of individual requirements and principles when creating project documentation wiring. Given that this issue is very voluminous content is not possible to describe all the principles, standards and requirements in the development of project documentation in detail. The next section focuses on the issue of intelligent building installations. Comparison between classical and intelligent installation wiring. Their advantages and disadvantages. Another part of this work focuses on the installation of intelligent, we chose the control system from Loxone. Its main parts, the way working and functionality that is able to perform. And the last part is the overall drafting of installation of the house, which is divided into classical and intelligent part.

Electrical installation in family house
Tesař, Jan ; Procházka, Petr (referee) ; Ondrejček, Vladimír (advisor)
This Bachelor Thesis is concerned with the design of the electrical installation of a family house. There are two main parts of the thesis – theoretical basis and the main design. In the theoretical part the reader is at first introduced to a powerline section, in which the electrical installation from the powergrid to a terminal equipment is described. Next part is about a low voltage wiring, where the commonly used types of wiring and devices are described. In the third part the reader can read about a lightning protection and its inner and outer parts. The main design consist of situational designs of devices and wiring in the house, switchboard designs, revision of the electrical protection and the technical report.
