This study describes the influence of distributed generation (DG) on a double-ended fault location based on measuring the high-frequency fault transients. The additional non-fundamental frequency current components from DG will influence the accuracy of an impedance-based fault location technique based on non-fundamental frequencies. A double-ended impedance-based fault location technique that utilises the high-frequency content (up to 5 kHz) is studied. This study showed that double-ended method is still able to locate a fault with a maximum error of 4% compared to the case without DG which showed a percentage error up to 2%.
