Abstract
A method for testing multiple spatially distributed protective devices of an energy supply network. Each of the protective devices is configured to, in the event of a fault occurring in the energy supply network, isolate the fault in the energy supply network. The method comprises: producing an initial test sequence; outputting of the test sequence to the protective devices; detecting outputs of the protective devices that the protective devices output on the basis of the test sequence; analyzing the outputs and generation of inputs for the protective devices depending on the outputs. If the inputs are not part of the test sequence, these inputs are incorporated into the test sequence and the outputting step proceeds. Otherwise, all outputs of the protective devices are evaluated. Each test sequence comprises inputs in the form of process variables of the energy supply network for at least one of the protective devices.
