Originální abstrakt

The article deals with the diagnostics of extinguishing process in low voltage devices by the means of pressure measurement in several points. The first part explains the technique of pressure measurement in switching devices and focuses on proper sensor properties and the problems of natural frequencies of the whole setup. The second part contains an example of pressure measurement analysis of the real device under real conditions, i.e. with the values of short-circuit currents in the range of tens of kA of prospective current with full voltage performed in the Laboratory of switching devices, Brno University of Technology. The last part compares the diagnostics method based on pressure measurement with other diagnostics techniques suitable for arc burning study under real conditions.
