In this article we show that the Total Harmonic Distortion (THD) of the current is a reliable index to identify the location of harmonic sources in a power system. It is proved that the harmonic estimators fail to identify harmonic source measurement errors. A 14 node system with two sources of harmonic solved by two methods is tested.
