Abstract: Described herein is a measuring apparatus including a first measuring unit operatively coupled to a first measurement point of the electric circuit, said first measuring unit configured to acquire first detection values related to one or more voltages at the first measurement point of said electric circuit; and a plurality of second measuring units operatively coupled to a plurality of second measurement points of said electric circuit, each second measuring unit configured to acquire second detection values related to one or more currents at a corresponding second measurement point of said electric circuit. The first measuring unit and the second measuring units are capable of communicating one with another, in a wired or wireless manner, in order to measure active electric power at said second measurement points. Also described herein is a method for measuring active electric power in an electric circuit.
