“…During arcing faults, the appearance of a long arc in free air must be modeled, i.e., the nonlinear nature of the arc should be considered and clearly represented. As it is mentioned in References [4,5], the unconstrained long fault arc in the air could be studied and modeled by applying the theory of switching arc, and based on that information, it is possible to develop a more precise model of arcing faults. In fact, the latest research only analyzes this phenomenon in the time domain, based on voltage and current waveforms [6,7].…”

“…A successful reclosing will occur when the secondary arc is self-extinguished before the DT. According to Reference [7], for a 500 kV system, this time varies between 0.4 to 0.5 s and can be obtained from Equation 1, which is a function of the TL voltage level VL [5].…”

“…During this time, reclosing will occur with or without the clear fault, so the extinction of the secondary arc must be ensured in this period. According to Reference [5], the secondary arc times measured in single-phase reclosing tests have shown a considerable dispersion around the average value, a high standard deviation, due to variation of physical factors. In this context, it is usually used as a safe DT of three times the average, about 1.5 to 2 s. The transient stability of the extra high voltage (EHV) TL is threatened by safe-long single-phase reclosing DTs, only because in unfavorable circumstances, the secondary arcs can last between 1.5 and 2 s [5].…”

Based on the Institute of Electrical and Electronics Engineers (IEEE) Standard C37.104-2012 Power Systems Relaying Committee report, topics related to auto-reclosing in transmission lines have been considered as an imperative benefit for electric power systems. An important issue in reclosing, when performed correctly, is identifying the fault type, i.e., permanent or temporary, which keeps the faulted transmission line in service as long as possible. In this paper, a multivariable analysis was used to classify signals as permanent and temporary faults. Thus, by using a simple convolution process among the mother functions called eigenvectors and the fault signals from a single end, a dimensionality reduction was determined. In this manner, the feature classifier based on the support vector machine was used for acceptably classifying fault types. The algorithm was tested in different fault scenarios that considered several distances along the transmission line and representation of first and second arcs simulated in the alternative transients program ATP software. Therefore, the main contribution of the analysis performed in this paper is to propose a novel algorithm to discriminate permanent and temporary faults based on the behavior of the faulted phase voltage after single-phase opening of the circuit breakers. Several simulations let the authors conclude that the proposed algorithm is effective and reliable.

“…According to Ecsanyi [12], the arc is extinguished at current zero, when the heat is extracted by the falling current. As the gas continues to fall it eventually de-ionizes the contact gap, at which point the dielectric strength needed to avert a re-strike is established [3]. [6,9].…”

The study of arc interruption is very essential in high voltage circuit breakers since arc extinction must be achieved in the shortest possible time for effective protection of the power system. This paper presents some conventional arc models used in the research of interaction between switching arc and circuit during the interruption process of high voltage circuit breakers. It goes ahead to develop a model that is current dependent with a constant time parameter that helps to improve the process of arc interruption in high voltage SF6 circuit breaker. The simulation results show that the model has the capability of reducing the arc interruption time by completely extinguishing the arc current almost instantaneously.

This paper proposes an efficient modeling and an identification method for dielectric barrier discharge (DBD) systems, based on input-output (current-voltage) experimental measurements. The DBD is modeled using an equivalent electric circuit associated with a differential equation that describes the dynamics of its conductance. This equation assumes a homogeneous behavior of the gas. This paper introduces a series of polynomial terms of the current of the gas into the conductance equation. These terms, after identification, are a very useful tool to analyze the physical mechanisms that take place in the gas. The identification process also returns the numerical values of other DBD parameters, such as associated capacitances and the breakdown voltage. In addition, an asymmetric model for the gas, which considers the direction of the current, is proposed to consider the possible geometrical dissimilarity between the two electrodes of the DBD setup. Experimental measurements taken on two different DBD applications are used for validating the proposed approach.
