Abstract:
A method for the contactless determination of an electrical potential of an object, involves providing an electrode which is spatially at a distance from the object, connecting the electrode to a reference potential, determining a first temporal change in an electrical state of charge of the electrode at a first value for the electric flux between the electrode and the object, determining a second temporal change in the electrical state of charge of the electrode at a second value for the electric flux between the electrode and the object, and determining the electrical potential of the object at least from the first temporal change in the electrical state of charge and the second temporal change in the electrical state of charge and from a difference between the first value and the second value for the electric flux.
