MESSVERFAHREN UND -SYSTEM FÜR ELEKTRISCHE GRÖSSEN

摘要

This method of measuring electrical quantities includes: - sending a synchronization message (66) on a data bus, by a synchronization module connected to the data bus, the sending being carried out with a transmission period (T _com ) counted using a first clock from the synchronization module; - reception of the synchronization message, by measurement modules connected to the data bus, each measurement module comprising a second clock and a sensor adapted to measure an electrical quantity; - the countdown, by each measurement module having received the synchronization message, of a first waiting time (t ₁ ), counting being carried out, for each of said measurement modules, using its second clock (48); - for each of said measurement modules, the measurement of the electrical quantity by means of the sensor corresponding to the end of the countdown of the first duration of wait (t ₁ ).
