The quality of electric energy in a low voltage public supply networks
Macoszek, Pavel ; Šlezingr, Jan (referee) ; Bok, Jaromír (advisor)
This thesis contains four main chapters, which describe qualitative parameters of supply voltage and measurement and analysis received information. The theoretical part consists of three chapters. Characteristics of low voltage are described in the first chapter. Next chapter describes disturbing events, which have influence on quality supply voltage, reasons for their occurrence spreading in network, eventually arrangement leading to the disappearance of disturbing events on other electric appliances in network. Last theoretical chapter describes measuring instruments of supply voltage. The purpose of these theoretical parts is to introduce the reader into supply voltage quality issues and can be used for preparation of measurement and evaluation of acquired data under norm ČSN EN 50160 (Voltage characteristic of electricity supplied by public distribution systems). An analysis of real network is the last part of this thesis. There is applied acquired knowledge with the aim of analysis of real states of qualitative parameters of supply voltage in network.

The quality of electric energy in a low voltage public supply networks
Vývoda, Marek ; Pithart, Jan (referee) ; Bok, Jaromír (advisor)
This thesis deals with description of qualitative parameters of supply voltage as well as measurement and data evaluation issues. Theoretical part of thesis describes basic characteristics of low voltage and limits based on standard specification. Next chapter deals with specification of measurement devices used for supply voltage quality measurement. The purpose of these theoretical parts is to introduce reader into supply voltage quality issues and can be used for preparation of measurement and acquired data evaluation under norm ČSN EN 50160 (Voltage characteristic of electricity supplied by public distribution systems). An analysis of real network is the last part of this thesis, in which application of acquired knowledge on assigment of real states of qualitative parameters of supply voltage in network.
