Abstract: A method and device for determining a division of a total insulation resistance and of a total system leakage capacitance in an ungrounded power supply system. The basic idea is to determine how the total insulation resistance is divided into partial insulation resistances and how the total system leakage capacitance is divided into partial system leakage capacitances between the active conductors of the ungrounded power supply system from displacement voltages measured between each of the active conductors of the ungrounded power supply system based on values determined in advance for the total insulation resistance and for the total system leakage capacitance of the ungrounded power supply system. By evaluating the displacement voltages in terms of their changes in amplitude, their frequency and their phasing, conclusions can be drawn as to the division of the total insulation resistance and of the total system leakage capacitance between the individual active conductors.

Abstract: A lightning protection system of a wind turbine (10) comprises electrically grounded receptors (51, 52) on turbine blades. A corresponding electrical ground connection must be tested regularly. For such a test, an unmanned aerial vehicle or UAV (4) places an electrode (41) near a receptor (51, 52). Using a high voltage generator (42), a high voltage is created between the electrode (41) and the receptor (51, 52), causing an electrical arc (45) between the two. A corresponding current through the lightning protection system (5) indicates whether the ground connection is in order. Thanks to the high voltage used, the electrical arc (45) can bridge a gap between the electrode (41) and receptor (51, 52) of at least several millimetres. It is not necessary to establish a direct physical contact between the electrode (41) and the receptor (51, 52). This simplifies controlling the UAV and speeds up the testing procedure.
