ANAL YSIS OF FAULT CURRENTS IN MEDIUM VOLTAGE (MV) POWER DISTRIBUTION LINES WITH SUPERIMPOSED COMPONENTS

Öz

In this study by using Superimposed Components method shunt

faults are analysed for overhead power distribution systems. By using digital

fault recorded data. fault inception time. fault path currents and the type of

fault are found. In the proposed method, possible presence or remote infccd

source and varying nature or loads and source capacities arc taken into

account. The results obtained lrorn the calculations arc compared with the

fault path currents obtained from a realistic distribution system which is

simulated with the well known EMTP simulation package. The results show

that the proposed method Can be effectively used for overhead power

distribution lines.
