Abstract

In this maximum-demand meter which consists of a kilowatt-hour meter and a maximum-demand mechanism, the maximum-demand mechanism is formed by a microcomputer with integrated memories. Information of the energy consumption by the kilowatt-hour meter is provided to the maximum-demand mechanism in the form of pulses. The microcomputer is controlled by external coding plugs and is customer-oriented in accordance with the requirements of the users. When the supply voltage drops below a certain value, a mains failure signal is also triggered which causes all data to be saved to be transferred into a non-volatile memory.
