ABSTRACT:
A high-voltage measuring device includes a grounded, cylindrical outer electrode (1) and an inner coaxial electrode (2) which has an at least approximately cylindrical shape and carries a high-voltage potential. A non-flat high-voltage resistor (3) which is arranged coaxially with respect to the inner electrode and is connected thereto. This resistor extends at least as far as the vicinity of the outer electrode. The response bandwidth and the loadability of the device substantially improved in that the high-voltage resistor is a cone shape envelope of uniform thickness such that the potential variation in response to current flow through the resistor corresponds to the electrostatic potential variation at least at the area of the inner electrode.
