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.

4. A controlled switching spark gap comprising:
-
a common base frame; a plurality of series-connected stages carried on the base frame and each having an individual spark gap, a resistor for potential control connected in parallel to the respective individual gap, and respective capacitors connected in parallel with the individual spark gaps; a respective auxiliary electrode connected to one of the individual spark gaps for external triggering; an additional damping unit carried on the frame, upstream or downstream of and in series with one of the stages, and comprised of a series-connected compensating resistor and compensating inductor, and a spark gap connected in parallel to the compensating resistor and inductor; a voltage divider on the base frame; and a single common head electrode for the damping unit and switching spark gap on the base frame.
