MEASURING SYSTEM FOR MEASURING AT LEAST ONE ELECTRICAL QUANTITY, ELECTRICAL TRANSFORMING STATION COMPRISING SUCH A MEASURING SYSTEM AND ASSOCIATED MEASURING METHOD This measuring system (20) is able to measure at least one electrical quantity relative to a power installation. The power installation comprises three electrical conductors able to enable the flowing of a three-phase alternating current. The measuring system comprises a voltage measuring element (66) for measuring 5 voltage of each of the electrical conductors, each electrical conductor being associated to a respective phase of the alternating network, an information processing unit (68) able to receive the values of the measured voltages, and three current sensors (76A, .. , 76N), each current sensor being able to measure the intensity of the current flowing in the corresponding electrical conductor. 10 The processing unit (68) comprises associating means (103) for associating in a predetermined manner the first measured voltage with a first phase among the three phases and a first identifying device (101) for identifying the phase corresponding to each of the two other measured voltages. The processing unit (68) comprises a second identifying device (125A, ..., 125N) for 15 identifying the phase corresponding to each of the three measured intensities. Figure 2 |
