The invention relates to a metering and measuring-point system for measuring and metering the electrical power/electricity which is tapped and/or supplied by a consumer/generator unit, at a fixed geographical point, from a tap-and/or-supply device. The system comprises one or more stationary tap-and/or-supply devices connected to the electrical grid and suitable for tapping and/or supplying electrical power/electricity which is tapped and/or supplied by consumer/generator units, as well as at least one identifiable and portable functional unit for measuring and metering the electrical power/electricity that is tapped or supplied, either conductively by means of an electric conductor or inductively, by consumer/generator units connected to one or more stationary tap-and/or-supply devices. A measurement device is associated with each of the plurality of tap-and/or-supply devices and is suitable for measuring at least one physical parameter that represents the electrical power transferred by each tap-and/or-supply device, and a measurement device is associated with said at least one functional unit and is suitable for measuring at least one physical parameter that represents the electrical power transferred between each tap-and/or-supply device and the consumer/generator unit with which said portable functional unit is associated. In addition, a means for comparison is provided which compares the at least one physical parameter measured on the connection side with the at least one physical parameter measured on the tap side and/or supply side. The invention also relates to a method for measuring, metering and billing electric current independently of location. |
