Development of Nottingham Arc Model for DC Series Arc Modeling in Photovoltaic Panels
IEEE Transactions on Industrial Electronics, 2022 This paper deals with driving effective DC series arc models from the original Nottingham arc model. The original Nottingham arc model has three constant parameters and suffers significant inaccuracy for modeling the series arc faults. To avoid the inaccuracy in the modeling, at first, a Nottingham model is developed that is relevant to voltage and ...

An Improved Arc Model Based on the Arc Diameter
IEEE Transactions on Power Delivery, 2016This paper introduces an improved electrical arc model based on the arc diameter variation. In the conventional arc models, the arc diameter is considered as an implicit parameter in arc model constants. In case of decreasing arc diameter along with the arc extinction, the arc voltage decreases as well. The arc diameter can be implemented as a function

Proceedings of the 27th Annual ACM Symposium on Applied Computing, 2009
The ARC (Agent, Role, Coordination) programming model is an evolutionary synthesis of established software technology that helps model-driven pervasive software applications to effectively utilize the parallelism on multicore processors. Computational entities in the ARC programming model are composed of role-based agents, exposing natural ...

ABSTRACT: This paper is an account of how arc modeling has increased our predictive capability of properties of arc plasmas. Basic material functions of, for example, thermal and electrical conductivities, can be calculated for any plasma, given the component elements of the plasma.

ARC flash hazard: the simplified model of ARC current
IEEE Systems Technical Conference on Industrial and Commercial Power 2005., 2005A simplified approach of arc modeling is suggested to facilitate the study of the dynamic behavior of the arc current. The behavior of the arc current is obtained as an extension of bolted short-circuit analysis; the waveform of the arc voltage is limited to the fundamental harmonic in phase with the fault current, considering the resistive ...

IEEE Transactions on Plasma Science, 2008
A 1-D model of the interaction between an electric arc and a solid refractory cathode has been developed. This model is based on the equilibrium of the charged particle fluxes in the cathode layer by considering current density conservation, and balance of energy at the sheath/presheath and at the sheath/cathode surface interfaces forming a closed ...

In this note, a modified Elenbaas-Heller equation [\textit{W. Elenbaas}, Physica 2, 169 ff. (1935) and \textit{G. Heller}, Physica 6, 359 ff. (1935)] is written in the frame of nonequilibrium thermodynamics. If the state of nonequilibrium of the plasma is near a state of equilibrium, it can be assumed that the plasma is in a state of local ...

Simplified arc-fault model: The reduction factor of the arc current
2012 IEEE Industry Applications Society Annual Meeting, 2012This paper presents a simplified model of arc fault that allows to analyze the dynamic behavior and to evaluate the RMS value of arcing fault current and the incident energy released by the electric arc. The study confirms previous results carried out in low voltage and medium voltage systems in different configurations, where the values of arcing ...

Plasma arc welding: a mathematical model of the arc
Journal of Physics D: Applied Physics, 1994A number of models of plasma arc welding have been constructed, including some that describe the arc itself. Relatively few rely solely on the physics of a plasma arc and the associated fluid dynamics for construction of mathematical models; for the most part they use a mixture of empirical results and basic physical principles.
