Methods and Apparatuses for Computation and Display of Equipment Operational Data

摘要

A method and system for displaying a characteristic of power associated with a first piece of electrical equipment that has an on-state and an off-state. A measurement of current consumed or produced by the first piece of electrical equipment in the on-state is received. Data derived from the current measured and associated times when the first piece of electrical equipment is in the on-state are stored on a memory device. A characteristic of power is calculated as a function of the data. A graphical representation (300) of the first data as a multi-dimensional shape on a graph having a first axis (302) with time increments and a second axis (304) with increments representing units of the characteristic of power is displayed on a video display (160). The multi-dimensional shape includes a first dimension representing a duration of the on-state and a second dimension representing the characteristic of power consumed or produced by at least the first piece of electrical equipment during the time period associated with the duration of the on-state.
