Claim:
1. Method for testing multiple spatially distributed protective devices of an energy supply network, wherein each of the protective devices is configured in order so as to, in the event of a fault occurring in the energy supply network, isolate the fault in the energy supply network, wherein the method comprises the following steps: a: production of an initial test sequence, b: outputting of the test sequence to the protective devices, c: detection of outputs of the protective devices that the protective devices output on the basis of the test sequence, d: analysis of the outputs and generation of inputs for the protective devices depending on the outputs, wherein, if the inputs are not part of the test sequence, these inputs are incorporated into the test sequence and step b is proceeded with, while otherwise step e is proceeded with, and e: evaluation of all outputs of the protective devices, wherein each test sequence comprises inputs in the form of process variables of the energy supply network for at least one of the protective devices.
