Electromagnetic field calculation inside a conducting cylinder of finite length using the T-Ω method
Springer Science and Business Media LLC - Tập 75 - Trang 419-424 - 1992
C. S. Antonopoulos, T. D. Tsiboukis, E. E. Kriezis
The solution of a 3-dimensional problem is, almost in all cases, a quite difficult task, since a great computational effort is required. AT-Ω method accompanied by a boundary element technique is presented for the evaluation of the field inside a conducting cylinder of finite length. The excitation is a current dipole with harmonic time variation (electric Hertzian dipole), located somewhere insid...... hiện toàn bộ

Elektrizitätsleitung in festen Dielektriken bei hohen Feldstärken
Springer Science and Business Media LLC - Tập 17 - Trang 609-624 - 1927
Hans Schiller
Es wird ein überblick über die bisher vorliegenden Untersuchungen über den Stromdurchgang durch Glas und Glimmer bei hohen Feldstärken gegeben. Die Versuchsergebnisse verschiedener Autoren werden miteinander verglichen. Die Abhängigkeit des spez. Widerstandes von der Feldstärke läßt sich für ein Feldstärkenintervall von I · 106 Volt/cm durch eine von H. H. Poole aufgestellte Beziehung gut darstell...... hiện toàn bộ
Influence of additional dielectric coatings on the electrode surfaces on selected parameters of acoustic emission signals in high-voltage gas insulation systems
Springer Science and Business Media LLC - Tập 104 - Trang 1741-1755 - 2021
Arkadiusz Dobrzycki, Władysław Opydo, Sebastian Zakrzewski
The paper is devoted to the study of impact of additional dielectric coatings placed on the surface of the electrodes on the operation of a high-voltage insulation system with air as insulating medium. The study mainly focused on measurement of partial discharges (PDs) with the use of acoustic emission method. Tests were conducted in various levels of chamber pressure. Applicable parameters of rec...... hiện toàn bộ

Bestimmung einer für Isolieranordnungen unter Öl zweckmäßigen 50%-Durchschlagstoßspannung
Springer Science and Business Media LLC - Tập 44 - Trang 52-56 - 1958
Volkmar Tetzner
Die Übertragung der für Isolieranordnungen in Luft gebräuchlichen 50%-DurchschlagstoßspannungU 50 auf Isolieranordnungen unter Ö1 ist nur bei einem—wirtschaftlich nicht vertretbaren—großen Zeitaufwand für die Messung einwandfrei möglich. Zur Charakterisierung der Stoßfestigkeit einer Isolieranordnung unter Ö1 wird daher eine etwa anders definierte 50%-DurchschlagstoßspannungU 50...... hiện toàn bộ

Arcing faults detection on power lines from the voltage and current signals
Springer Science and Business Media LLC - Tập 79 - Trang 213-218 - 1996
M. B. Đurić, Z. M. Radojević, V. V. Terzija
To avoid automatic reclosing on permanent faults, a new digital algorithm for arcing faults detection has been developed. Some important features of a long arc in the air are investigated and used as a base in the algorithm design. The fact that the nonlinear arc behavior influences other voltages and currents distorting them, offered an opportunity to detect the arc by measuring and processing th...... hiện toàn bộ
