This use-case aims at improving the location of faults at distribution lines, close to the interface with the transmission network. Concretely, the focus is on distribution lines, owned and operated by the DSO, that are directly connected to transmission bays, owned and operated by the TSO.<br/><br/>In such cases, by having access to information available at the TSO side, collected in transmission bays connecting distribution lines, the DSO will be able to improve the location accuracy of faults on its own distribution lines. This requires additional information to be exchanged in real-time between both system operators. <br/><br/>The real-time exchange of data from the TSO to the DSO for fault location purposes is the motivation of this use-case with the ultimate goal of optimizing operations on the DSO side.<br/>
