ABSTRACT:
A power monitoring system with associated signal processing and storage capabilities. Impulses that are superimposed on an alternating-current electrical signal are identified and evaluated based upon amplitude, duration, and phase position. Impulses that are not substantially similar to impulses on immediately preceding cycles of the input signal are recorded. In a further embodiment, if a series of substantially identical impulses occurs, a count of the number of impulses is stored, and detailed data is stored for only the first impulse in the series. In another embodiment, the impulses are ranked according to a quality factor, and data for the impulse with the lowest quality factor is deleted from a storage device when the device becomes full.
