Abstract
Current and voltage waveforms on the branches of each node of a power distribution network are sampled. The samples are converted to digital signals which are resolved into spectral components and processed to obtain the power (KVA) phasor at each frequency (harmonic component) of interest. The phase angles of the phasors describe the directions of movement, and thereby the locations of the sources, of the power harmonics in the network. A summary report is generated.
