Abstract
A device for measuring a quantity such as the electric power in a polyphase alternating current network including at least two phase conductors and a reference conductor, of the type comprising two measuring devices which are associated respectively with the two phases and the outputs from which are connected to a summation device. A supply circuit connected to one of the phases is associated with the corresponding measuring device, and a device connected to the other phase ensures the supply to the other measuring device and to the summation device, the supply circuit and the supply device being connected through a high-impedance tie circuit, the summation device being supplied if at least one of the phases is under voltage with respect to the reference conductor.
