This paper dealswith voltage sags, which are reflected in the aspect of power quality. During a voltage sag, the voltage at the customer terminal is reduced and can cause undesirable equipment trips. The main causes of voltage sags are short-circuit faults. Most short-circuits in a power system are either single line-to-ground or two phase short circuits. The causes of voltage sags in the power system are not the subject of this paper. This paper analyses the propagation of single-phase voltage sags caused by a line-to-ground short circuit in a transmission network, from the high voltage level to the distribution level through various types of transformers. The influence of the transformer winding connection on the propagation of voltage sag is investigated from the theoretical aspect, the practical aspect and the computer simulation aspect. One example of voltage sag propagation from the transmission network to the distribution network that is captured with the power quality measurements is analysed. Theoretical calculations of voltage sag propagation through the various types of transformer windings connections are presented and compared to the measurement result. Furthermore, a computer model of the observed distribution network is modelled in DigSILENT Power Factory software. This model is used for the simulation of voltage sag propagation. The results of the computer simulation are presented and comparedto the measurements. Conclusions and comments on the results are presented at the end of the paper"},{"@xml:lang":"sl","#text":"Kakovost električne energije je zelo pomemben vidik pri razdeljevanju električne energije. Ta članek se ukvarja z upadi napetosti, ki predstavljajo en vidik kakovosti električne energije. Med upadom napetosti je napetost na uporabniškem priključku znižana in lahko povzroča neželene napake opreme. Glavni vzrok upadov napetosti so kratkostične okvare. Večina kratkih stikov v omrežju je enofaznih zemeljskih ali dvofaznih. Vzroki upadov napetosti v elektroenergetskem sistemu niso predmet tega članka. Članek predstavlja analize širjenja enofaznih upadov napetosti zaradi enofaznih zemeljskih kratkih stikov v prenosnem omrežju, od nivoja visoke napetosti do nivoja napetosti distribucije preko različnih tipov transformatorjev. Vpliv vezave transformatorskega navitja na širjenje upada napetosti je raziskan iz teoretičnega vidika, praktičnega vidika in vidika računalniške simulacije. Analiziran je en primer širjenja upada napetosti iz prenosnega omrežja na distribucijsko omrežje, ki je zajeto z merjenjem kakovosti električne energije. Teoretični izračuni širjenja upada napetosti preko različnih tipov vezav navitij transformatorja so predstavljene in primerjane z rezultati meritev. Prav tako je računalniški model opazovanega distribucijskega omrežja modeliran v DigSILENT Power Factory programski opremi. Računalniški model je uporabljen za simulacijo širjenja upada napetosti. Rezultati računalniške simulacije so predstavljeni in primerjani z meritvami.
