Abstract

An electrical utility meter includes a controller that determines a list of highest demands using event-triggered windows of time to ensure that only one of the entries on the list corresponds to any one high consumption event. The controller generates a demand value corresponding to the quantity of energy consumed within a demand interval, and then determines whether the demand value for the demand interval is greater than a smallest demand value on a list of highest demands in a memory location. If so, the controller opens a demand window, the demand window having a duration exceeding the demand interval. The controller then obtains a plurality of additional demand values for the duration of the demand window, each of the additional demand values corresponding to one of a plurality of additional demand intervals within the demand window. The controller records in the list of highest demands in the memory location a select one of the demand value and plurality of additional demand values. The select demand value may suitably be the largest demand in the window.
