Parameterization of electric appliances immunity curves to voltage dips and short interruptions
Šlezingr, Jan ; Bok, Jaromír (referee) ; Drápela, Jiří (advisor)
This master’s thesis work deal with diagnosis parameters immunity curves uniphase appliance on short - term voltage dips a interuption. Immunity curve is dependence smallest possible sizes RMS voltage for performance given to criteria function on time continuation voltage event. Curves of resistance is different for each electric appliance, and depending on the size and over-voltage network, the burden on resources and voltage during the event.. The goal of this work is to devise a methodology for measuring the implementation of parametric measurement limit curves of resistance for selected types of appliances.
Evaluation of voltage events regarding to immunity of electric appliances
Švindrych, Jan ; Bok, Jaromír (referee) ; Drápela, Jiří (advisor)
This diploma thesis deals with evaluation of voltage events regarding to immunity of electric appliances. This thesis is divided into three logical sections. In the first part are shown the voltage events, their definitions, causes and spreading in the mains. The second part deals with measurements and existing possibilities of evaluation of voltage events. The third part deals with suggestion of new evaluation of voltage events regarding to immunity of electric appliances and verification in practice.
