Current sensor signal processing using microcontroller
Tlustoš, Luboš ; Chytil, Jiří (referee) ; Friedl, Martin (advisor)
In this thesis is described Wiegand wire, current sensor using Wiegand wire effect and processing the output signal from the current sensor using a microcontroller. The document is divided into chapters, each of which are generally described microcontrollers and their applications to signal processing. It also describes the design of circuits for generating sine wave, circuits for appropriate adjustment of the output signals from the sensor current and a draft power source.

Analysis of the electrical power measurement system in the local distribution network Pod Palackého vrchem
Hájková, Barbora ; Orságová, Jaroslava (referee) ; Jurák, Viktor (advisor)
The diploma thesis introduces a detailed analysis of the local distribution system (LDS) Pod Palackého vrchem (PPV) in the Brno, parameters of power transformers and cable routes between them. The elements of the electrical network that are influencing the balance of reactive power are described along with its sources and appliances. In the next part is defined the present concept of long-term measurement in the LDS by using current and voltage sensors. This part deals with calculations of power losses in the power transformers and the cable lines together with uncertainties concerning power measurement in the field of energetics. The essential part of the thesis focuses on the analysis of the temporary measurement implementation in the LDS, data processing along with the comparison of measured values from temporary measurement with values from permanent measurement. In conclusion, the error of the system is determined.
