The model was verified by comparing the simulation results with electric field and current measurements. At the outset, the ideal case, where a homogeneous initial charge carrier distribution according to the definition of ohmic conductivity is present, is analysed to establish the preliminary foundations pertaining to a typical measurement. Following that, the influence of distinct charge carriers on the measured quantities are investigated by altering their parametrisations. In contrast to the ideal case, a real measurement reveals a current trend, that can be explained by an excess amount of initial charge carriers related to the oil-impregnated pressboard layers. Potential possibilities to the origin of the surplus are discussed. Furthermore, it is shown that the dissociable and intrinsic charge carriers alone can reconstruct the measured quantities in terms of the transient behaviour. This points out that, for the field strength studied here ( E ≤ 1 kV/mm ), the charging of the highly resistive pressboard barriers is dominated by the dissociation of charge carriers in the oil gaps.}, language = {en} } @article{ZinkKuechlerBerger, author = {Zink, Markus H. and K{\"u}chler, Andreas and Berger, Frank}, title = {Kompensation des Temperatureinflusses auf dielektrische Messungen im Zeitbereich zur Beschreibung von Isolierwerkstoffen}, series = {ETG-Fachtagung „Grenzfl{\"a}chen in elektrischen Isoliersystemen"}, journal = {ETG-Fachtagung „Grenzfl{\"a}chen in elektrischen Isoliersystemen"}, address = {Dresden}, language = {de} } @inproceedings{WirthSturmKuechleretal., author = {Wirth, Isabell and Sturm, Sebastian and K{\"u}chler, Andreas and Zink, Markus H. and Berger, Frank and Schnitzler, Tim}, title = {Ber{\"u}cksichtigung von Leitungs- und Polarisationsmechanismen in transienten FEM-Simulationen von HG{\"U}-Isoliersystemen}, series = {VDE-Hochspannungstechnik 2018, Berlin}, booktitle = {VDE-Hochspannungstechnik 2018, Berlin}, abstract = {The calculation of electrical field distributions in insulation systems for high voltage direct current (HVDC) transmission using the finite element method (FEM) usually only considers the dielectric properties in the form of permittivities and conductivities. Due to not sufficiently well simulated transient processes, state of the art is considering the polarization processes by equivalent network models. The application and implementation of polarization mechanisms in a FEM soft- ware closes this gap and allows calculating the electric field distribution more precisely. An implementation of additional differential equations, according to the RC-network model, describing the field dependent polarization mechanisms, are complementing the displacement and conduction current. Material equations and their parameters are determined by measuring the polarization and depolarization currents (PDC). These equations are necessary for both the RC-network models and the differential equations for the FEM. They can be adapted to the actual temperatures in the insulation system. Hence, the necessarily multidimensional electric field calculations of complex insulation systems with stationary or transient temperature-gradients are possible. The described calculation method is verified by reactionless fieldmill voltmeter measurements of transient voltage profiles at the grading foils of modified high voltage DC-bushings. A better accuracy is achieved for the simulation of transient and stationary potential distributions.}, language = {de} } @inproceedings{KochHohlochWirthetal., author = {Koch, Myriam and Hohloch, Jens and Wirth, Isabell and Sturm, Sebastian and Zink, Markus H. and K{\"u}chler, Andreas}, title = {Experimental and simulative analysis of the thermal behavior of high voltage cable joints}, series = {VDE-Hochspannungstechnik 2018, Berlin}, booktitle = {VDE-Hochspannungstechnik 2018, Berlin}, abstract = {Nowadays, cable systems are often preferred when deciding on the type of new transmission lines even in the high and extra high voltage range. One of the main reasons is the better public acceptance. In addition, the power to be transmitted in the grid is increasing leading to increased ohmic losses and thus, to higher thermal stress on the materials. The investigations in this contribution focus on cable joints, which represent important and decisive components of cable systems. In order to optimize the design and to ensure reliable operation over the entire service life, the temperature profile within these components is of special interest. For their detailed investigation, a test circuit was set up consisting of a cable section and sections with build-up stages of a cable joint. A large number of measuring points were defined also at points where no measurement is possible in normal operation. With a thermographic camera the surface temperature distributions were observed. With the laboratory setup temperature profiles under various load conditions were recorded. A detailed FEM model was built and verified with help of these measurements. The model permits the investigation of specific questions of cable systems such as the comparison of temperature loads resulting from normal operating conditions and of test procedures according to the relevant standards. Besides others the effect of stressing the insulation and sealing system by heating the inner conductor vs. heating from outside by surrounding water is discussed.}, language = {en} } @article{ZinkKlipfelBergeretal., author = {Zink, Markus H. and Klipfel, V. and Berger, Frank and K{\"u}chler, Andreas and Voll, S.}, title = {Der Einfluss von Temperatur und Streukapazit{\"a}t auf diagnostische Kapazit{\"a}ts- und Verlustfaktormessungen von 400 kV-Hochspannungstransformatordurchf{\"u}hrungen}, series = {ETG-Fachtagung „Diagnostik elektrischer Betriebsmittel"}, journal = {ETG-Fachtagung „Diagnostik elektrischer Betriebsmittel"}, address = {Fulda}, language = {de} } @inproceedings{WirthHessdoerferKuechleretal., author = {Wirth, Isabell and Heßd{\"o}rfer, Nadja and K{\"u}chler, Andreas and Zink, Markus H. and Langens, Achim and Berger, Frank}, title = {Measurements and calculations of critical thermal and electrical stress conditions for HVDC bushings}, series = {20th International Symposium on High Voltage Engineering, Buenos Aires, 2017}, booktitle = {20th International Symposium on High Voltage Engineering, Buenos Aires, 2017}, language = {en} } @inproceedings{HopfWirthSturmetal., author = {Hopf, K. and Wirth, Isabell and Sturm, Sebastian and K{\"u}chler, Andreas and Zink, Markus H. and Langens, Achim}, title = {Temperature-dependent and anisotropic electrical conductivity of resin-impregnated paper}, series = {Power and Energy Student Summit, N{\"u}rnberg, 2017}, booktitle = {Power and Energy Student Summit, N{\"u}rnberg, 2017}, language = {en} } @inproceedings{WirthKuechlerZinketal., author = {Wirth, Isabell and K{\"u}chler, Andreas and Zink, Markus H. and Berger, Frank and Langens, Achim}, title = {Elektrische Feldverteilung und Polarisationsstr{\"o}me in HG{\"U} Durchf{\"u}hrungen}, series = {Fachtagung Polymere Isolierstoffe und ihre Grenzfl{\"a}chen, Zittau, 2018}, booktitle = {Fachtagung Polymere Isolierstoffe und ihre Grenzfl{\"a}chen, Zittau, 2018}, language = {de} } @incollection{KuechlerSchoberHarreretal., author = {K{\"u}chler, Andreas and Schober, F. and Harrer, S. and Krause, Ch. and Berger, Frank}, title = {Einfluss von Temperatur und Ligningehalt auf die elektrische Leitf{\"a}higkeit von Pressspan als HG{\"U}-Isolierwerkstoff}, series = {6.
