“…Most of the published works on black box models are based on the well-known Cassie and Mayr models [6,7] which provide a qualitative description of the arc in the high-and low-current regions, respectively. Also, several approaches to arc modeling that combine Cassie and Mayr models for representing the electric arc dynamics in a wide current region have been proposed in the literature [8] and by the authors [9].…”

A new method for calculating the parameters of electric arc models for power circuit breaker is developed. The methodology consists in the optimization of the theoretical arc voltage curve, as a function of a set of parameters, with respect to experimental data. Since the solution of the equation for the electric arc model cannot be obtained in general form, then, the theoretical arc voltage is an asymptotic solution obtained for one or several time-ranges. A case of the irregular behavior of the electric arc is analyzed. The developed methods are applied to obtain an improved arc model for a SF 6 power circuit breaker previously published in the literature. The new model has a compact form and exhibits a good correlation between the measured and calculated voltage curves.

“…Figure 11 presents the primary and secondary equivalent interfering current variations caused by different pantograph arc voltages. Figure 12 presents the relative harmonic copper loss which was defined in Equation (22). In Figures 11 and 12, because the excitation current is negligible compared to the primary and secondary currents, the variations trend of the equivalent interfering current and harmonic copper loss of the primary windings and secondary windings stay nearly the same.…”

Abstract:The traction transformer of the traction drive system of a high-speed train is one of the main equipments for energy conversion. The transformer loss will be increased by load harmonics and pantograph arcs at high speed. It is very important to predict losses for the improvement of traction transformer design. In this paper, a dynamic model of the pantograph-catenary system is established using the MSC.Marc software based on the finite element method to analyze disconnection events in different speeds. Then the pantograph arc, traction transformer and four-quadrant converter model is set up. Resistance variations with the change of harmonic frequency have been considered in the calculation formulae of harmonic losses. Traction transformer losses can be calculated based on the harmonic T-equivalent circuit and superposition principle. Considering the harmonic losses variations, the effects of arc voltage on harmonic copper loss and harmonic core loss are analyzed, respectively. The average loss at different disconnection ratios is also calculated. This method could be used to estimate the increment of transformer harmonic losses with poor current conditions at high speed.

Summary This paper deals with different failure mechanisms in a synthetic test circuit, which may lead to faulty interpretation of the results achieved using such a synthetic test circuit to evaluate the current interruption capability of high‐voltage circuit breakers. These include transient insulation failure in different components of synthetic test circuits supposed to high voltage as well as imperfect operation of various switches. Different failure modes are simulated and it has been shown that the simulation results match the waveforms measured in faulty operational circuits. The results of this paper make it possible to distinguish different failure modes of such circuits based on the measured current and voltage waveforms. Copyright © 2014 John Wiley & Sons, Ltd.
