The invention concerns a method and equipment for the compensation of voltage increase in electrodes of a 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 a 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.
A method of compensating voltage increases in a dielectric material processing apparatus having at least two rod-like parallel electrodes connected to opposite ends of a source of radio frequency signals comprising:
In combination with a dielectric material processing apparatus having a plurality of parallel electrodes excited at one end by a source of radio frequency signals, an equipment for compensating voltage increases comprising:
