Abstract

Very often in distribution systems many small loads of the order of 100KVA or less are fed from same feeder. A fault at one load drastically affects the loads even at far end. Here the effect of L-G and L-L faults followed by an Open conductor fault (fuse blow off in one phase) at the remote load point is presented for different feeder X/R ratios. The restoration of supply voltages using a DVR (with Space vector control) at the desired load point is studied.
