Abstract: A method for distributed electrical power determination of at least one consumer connected to a voltage source via a voltage path, where a voltage measurement device determines a supply voltage of the voltage source at a voltage measurement point and at least one current measurement device determines a consumer current of the consumer at a current measurement point. The method comprises recording measured values of the supply voltage to determine a voltage curve of the supply voltage, recording measured values of the consumer current to determine a current curve of the consumer current, analyzing the measured values of the supply voltage and/or the measured values of the consumer current with an analysis function to determine voltage characteristics of the voltage curve and/or current characteristics of the current curve, and determining at least one power value taking into account the voltage and/or current characteristics.

Abstract: Measuring data are provided for monitoring a current-supply network, based on one or a plurality of measured electrical quantities of the current-supply network. A time signal is assigned to the measuring data. The measuring data are inspected for the occurrence of one a plurality of predetermined events. Based on determining the occurrence of predetermined event or events, corresponding event data based on the measuring data are generated. A time stamp is conferred to the event data, where the time stamp is based on a link of a synchronized clock time provided by a clock and the time signal assigned to the measuring data. User data are generated from the event data comprising the time stamp, and transmitted via a communication network.
