Abstract
A power monitoring system with associated signal processing and storage capabilities. Each leg of a three-phase power signal is simultaneously sampled on a plurality of channels to capture the instantaneous content of the power signal without time-skewing between the channels. In a further embodiment, the sampled data is converted into the frequency domain and parameters relating to the power quality of the power signal is derived from frequency-domain data.
