Abstract: The present invention relates to a test system for high-voltage technology devices, in particular shunt reactors, as defined in the preamble of independent patent claim 1. The invention also relates to a method which can be carried out with this test system and is intended to test high-voltage technology devices according to coordinate patent claim 5. The general idea of the test system according to the invention is to provide a continuously adjustable inductance and a capacitance, which can be adjusted in discrete steps, on the secondary side of the test transformer in such a manner that said components form a series resonant circuit together with the test object in the form of an inductance.

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.

Abstract: A correction algorithm is used in order to reduce the systematic measurement error arising from the evaluation device of an impulse voltage test system. It is advantageous to install the high-voltage divider as intermediate circuit. This arrangement requires only one high-voltage connection between the components of the test system and the device under test. The correction function uK(t) is the difference between the voltage at the device under test uP(t) and the voltage at the high-voltage divider uT(t).
