Abstract
A power monitoring system with associated signal processing and storage capabilities. An input signal is sampled and the samples are used to derive total harmonic distortion, total power, and reactive power. Parameters of the input signal at a selected time are displayed as a vector superimposed on a three-axis graph having total power as one axis, reactive power as the second axis, and total harmonic distortion as the third axis.
