“…Black box models [6] are the most common approach, which treats the arc as a black box relating electrical conductance and arc energy. It has been argued that the thermal energy is the key factor that keeps an arc blazing so that the conductance can be reflected by thermal balance (assuming that the energy of the arc is associated with the thermal balance).…”

This paper proposes a mathematical model for electrical discharge plasmas between moving electrodes under ac condition, which happens in ac switching apparatuses. The modeling work is started by converting the problem to a conventional RL network that treats the arcing phenomenon as a black box and proposing a transient differential equation to represent the breaking arc process. A resistance-time relation model developed from the classic Mayr model is then proposed. A conceptual unit-arc approach is used to deal with the issue of variable arc length as the contacts move. Experimental data from ac contactor tests are used to approximate the resistance-time function by a nonlinear curve fitting. The model is solved computationally and compared with the experimental data. It is that the model adequately describes the breaking arc phenomenon. . His current research interests include data analysis on electrical apparatus, including arc modeling, reliability, endurance prediction, fault detection, electric automatization and intellectualization, including applications of automatic and intelligent manufacturing, and industrial image processing.Guichu Wu is currently the Director of the

“…The issue is not avoided if, instead of an arc model in terms of its characteristic, a model in terms of an equivalent arc resistance is used, as has been done in the literature [6][7][8][9].…”

“…A mathematical algorithm is proposed for model parameter optimisation that involves solving a non‐linear least squares optimisation problem by suitably coupling gradient moves with the investigation of approximate value by heuristic search methods. The Levenberg–Marquardt algorithm (LMA) was applied to the Schwarz model to perform reliable and precise arc modelling [2, 3].…”
