Claim:
1. A system for detecting an electrical fault in an electrical installation comprising several electrical conductors, the system comprising: at least two measurement modules, each measurement module comprising first radioelectric communication device, a sensor for measuring each electrical magnitude associated with a corresponding electrical conductor and a first clock defined by a first initial instant and a first clock frequency, each measured value being suitable for being associated with a first instant of measurement, determined with respect to the first initial instant and as a function of the first frequency, an acquisition unit for acquiring the measured values, comprising second radioelectric device adapted for communicating with the first radioelectric communication device, said system further comprising, for at least one of the measurement modules, a member for detecting the electrical fault associated with the corresponding electrical conductor, the detection member being suitable for determining the value of an instant of detection of the fault with respect to the first initial instant and as a function of the first frequency, wherein the acquisition unit comprises: a first determination device for determining the value of each instant of detection with respect to the first initial instant and as a function of the first frequency of the other measurement modules, a device of acquisition for each measurement module of solely the measured values for which the first instant of measurement lies in a corresponding first predefined time interval, each corresponding first interval comprising the value of the instant of detection determined for the said measurement module with which it is associated.
