Abstract :
This paper analyzes a disturbance effect that occurs at measurement setups with looped ground connections. It is shown how this effect arises by measuring it with a special setup. Further the effect is deconstructed in detail using a simplified model. Hence steps to be taken are shown in order to suppress this disturbance effect.
