摘要： According to an example aspect of the present invention, There is provided detecting hidden faults in distribution networks. When input flow and output flow of the distribution network indicate a hidden fault, location of the hidden fault is determined by determining one or more pressure distributions based on the hidden fault being located at a proposed location of the distribution network. Then differences of the determined pressure distributions are determined with respect to a reference pressure distribution and the location of the hidden fault is determined in the proposed location, where the difference between the pressure distribution corresponding to the proposed location and the reference pressure distribution is the smallest.
