  • Switching spark gap
    Patent number: 8344554
    Abstract: The present invention relates to a controlled truncating radio connection for a high-voltage impulse test system, preferably for quality assurance of power transformers. According to the invention, the truncating radio connection is expanded by an additional damping unit, made of a serial damping resistance and a damping inductance having a radio connection connected in parallel thereto, and thereby combines the functionalities of a truncating radio connection and an overshoot compensation in only one auxiliary component.
    Type: Grant
