Abstract:
In order to determine the occurrence of a fault, notably transient, in an electrical distribution network, a method and a device are developed based on the determination of the frequency (f) of the current signal circulating in a phase of the network. Notably, the difference between the determined frequency (f) and the natural frequency (f0) of the network is compared to a threshold.
