Abstract
The invention relates to a device (20) with an electrical device having at least one region (6) and a first coil (12), wherein the region, the during operation of the electrical device (2), is at least temporarily loaded with a fluctuating electrical potential (7) and can be coupled via a first capacitive coupling portion to a first electrical potential (15). The region is conductively connected via the first coil to a first connection point. The electrical device comprises at least one extension portion (24) with an end region and a second coil (26). The end region is conductively connected to the first connection point via the second coil and can be coupled to the first electrical potential (15) via a second capacitive coupling portion, wherein the end region is not conductively connected to the electrical device in addition to this. An inductive coupling portion, the second coil, the second capacitive coupling portion, the first capacitive coupling portion and the first coil are matched to one another such that a parasitic current flowing through the first capacitive coupling portion substantially corresponds to an inverse current flowing through the second capacitive coupling portion.
