Abstract
A method and device for monitoring an electrical network, including: a mechanism detecting electrical signals and additional signals produced in the electrical network, the additional signals being of a different physical nature to the electrical signals; a mechanism for processing the electrical signals to define a first time reference representing a detection time of the electrical signals emitted upon a fault event arising in the electrical network; a mechanism processing the additional signals to define a second time reference representing a detection time of the additional signals emitted upon the fault event arising in the electrical network; and a processor spatially locating the fault event in the electrical network according to the first and second time references.
