US 6,604,055 B1 · System and method for AC line voltage analysis

Abstract

A system and method for AC line voltage analysis is disclosed. According to one embodiment of the present invention, a system for AC line voltage analysis on an AC line includes a transformer that steps down the AC line voltage, a rectifier that rectifies the stepped down AC line current, a filter that filters the rectified AC line current, a voltage divider that reduces the AC line voltage; and an A/D converter that converts the reduced AC line voltage to digital bits. According to another embodiment of the present invention, a method for AC line voltage analysis of an AC line includes the steps of (1) calibrating equipment for measuring AC line voltage analysis, (2) adjusting for at least one load, (3) filtering an adjusted measurement; and (4) determining an actual line voltage.
