Vyhodnocení dat z elektroměrů s možností měření parametrů kvality

Abstract

The theme of this work is to obtain a reduced data file created from retrieved data from electrometer with the possibility of measurement of the electricity quality. The obtained reduced data file has identical informative value. The measurement point is located to the delivery place connected to the local grid. With regard to the intended application, there is dedicated particular attention to the power voltage (UC) in each phase, frequency, supply voltage, assessed using the harmonic voltages the total harmonic distortion factor THD, voltage interharmonics, quick change voltage, power interruption, voltage drop (UC < 90 % Un) or its duration, temporary interruption ( turn on again, to 5 sec. ), transitional overvoltage, voltage fluctuations, a temporary voltage increasing in given frequency (UC > 110 % Un) or its duration, voltage asymmetry and voltage variation.
