Claim:
1. A method for detecting a device that generates spurious signals in an electrical network, to which several devices and at least one fault detection device are connected, comprising the following steps: acquiring an electrical spurious signal in the electrical network; sequentially influencing the power supply of the devices one after another, each for a predetermined time, via the electrical network, and correspondingly checking the electrical network for any change in the respective electrical spurious signal resulting from this influencing until such time as the respective spurious signal changes; and signaling at which one of the devices the respective spurious signal changed, wherein the predetermined time is selected in such a way as not to limit the function of the respective at least one of the devices subjected to a sequential influencing of the power supply while its power supply is being influenced over the predetermined time, or wherein the predetermined time is selected in such a way as to limitedly maintain the respective at least one of the devices subjected to a sequential influencing of the power supply while its power supply is being influenced over the predetermined time.
