Patent ID: 7216058

Claim:
A method for permitting an on-site diagnosis of the performance and/or production activity of one or more units of electrical equipment in a facility by a shop, building, plant or factory to determine if power is being wasted comprising the steps of: measuring the consumption of electricity in said one or more unit(s) of electrical equipment in kwh or another conventional measuring unit; displaying time along two different coordinates corresponding to two separate axes which intersect one another for forming a time grid with the time displayed along one of the coordinates being interrelated to the time displayed along the other coordinate in a fixed relationship; dividing the time displayed along each coordinate into a multiple number of time segments corresponding to the operation time of said one or more unit(s) of electrical equipment over a first time interval for one of said coordinates and over a second time interval for the other coordinate with the time segments in the first time interval corresponding to only one or a small number of time segments in the second time interval; and displaying the measured consumption of electricity for said one or more unit(s) of electrical equipment at a location for each time segment in said first and second time interval at each intersection of the two time coordinates such that an on-site determination of the operating condition of said one or more unit(s) of electrical equipment becomes visually apparent from the display.
