ABSTRACT:
A solid-state demand register is described for determining the maximum electrical-power demand made on an electric utility by a load. The register, which employs a microprocessor, provides noncumulative, cumulative, and continuous-cumulative electrical-power demand measurement capabilities. The microprocessor, operating under a control program stored in a read-only memory, employs computing constants and generates computed results. A nonvolatile read/write memory, which stores the computing constants and computing results, is of the type that retains stored data even when deenergized. These constants and results can be visually displayed by an optoelectronic display. Error detection and correction of data are performed by the programmed microprocessor by means of an eight-bit Hamming code. The register further includes pulse generators for generating pulses indicative of the electrical-power demand and the end of a demand-monitoring time interval, and includes a controller for inhibiting the optoelectronic display when the ambient light adjacent the controller falls below a preselected threshold level.
