The invention concerns a method and equipment for the compensation of voltage increase in electrodes of an apparatus used to process dielectric materials. In the apparatus the electrodes are arranged parallel, at a constant distance from each other across the conveying path of the material to be treated. Electric power to the electrodes is supplied by connecting the adjacent electrodes to an opposite pole of a high frequency power source. In order to minimize the voltage increase in the electrodes, a reverse magnetic field is brought to influence with the magnetic field of each electrode, by arranging a return path for the electrode current at a suitable distance from the electrode and connecting these return paths to the return paths of the adjacent electrodes. |
