Electrical power distribution system

Abstract

Abstract An electrical power distribution system, for example for building sites, is specified, which has a power supply (8) and a multiplicity of consumer connections (7A to 7N) which are connected to the power supply (8) via supply leads (A to N), safety-switch devices (6) and a corresponding enable device (5). The enable device (5) is connected to a consumer meter (4) and to a computer (3), a reading/coding device (2) is connected to the computer (3) and reads the user-specific content of charge-cards (1), reduces the value of the charge-cards with respect to the usable quantity of energy and updates this at the end of a period of consumption. The computer (3) stores the content of the respective charge-cards (1) for each user and consumer separately and controls the operation of the enable device (5) for each consumer connection as a function of the value read in separately for each user, in such a way that each user can use power only after entry of a valid charge-card and, at the end of his respective period of use, obtains the remaining residual value credited on his charge-card (1). <IMAGE>
