ABSTRACT:
A load demand control system for limiting the total average electric load over a moving predetermined time interval to an installation having at least one large load device, making use of a timer control which can be selectively operated by an operator upon the need for the operation of the one large electrical load. The timer control first resets the control point of the load demand control of the installation at some low predetermined value. Subsequently, the timer control turns on the large load for a predetermined period of time and after its operation, the timer control maintains the low predetermined value of the load demand control for a further predetermined time period whereby the total moving average electrical load to the installation for the total time interval of the timer control is maintained below a predetermined peak electrical load value set for the installation.
