In this paper, two fault location methods in a real 205-nodes distribution feeder have been compared. The applied fault locationalgorithms are impedance and travelling based methods. The investigated algorithms have some meaningful diff erenceswhich researchers fi nd interesting. Most importantly the number and types of measuring devices for logging the voltage/current at a set relay point and at a particular sampling rate. Due to the fundamental component of voltage and current duringa post-fault impedance based algorithm, both voltage and current recorders have been installed with a low sampling rate. Ina travelling wave based algorithm, they voltage recorder uses high sampling rate. The accuracy of the algorithms have beenvalidated by several simulated fault studies carried out in EMTP-RV software on a 205-nodes 20 kV real radial distributionfeeder. In order to show the capabilities of each method, the simulation results have been presented in diff erent cases suchas fault type, fault resistance, fault inception angle and existence of distributed generation.
