Abstract
A method and apparatus are described for determining the charcteristics of an alternating current electrical service at a remote panel as compared with a main panel from which the remote service is connected. The method involves the steps of selecting a line at the main panel and designating it as the reference. The phase relationship of other lines at the main service panel are determined relative to this reference by a process of deriving the period of the signal on the reference line, and from this point the phase relationship of the other line signals are determined. A counter is loaded with a value representative of the derived period of the reference signal, and finally, the characteristics of the individual service line signals at a remote location are determined by a step of comparing each with the characteristics derived for the main service panel.
