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 ...

A DC Arc Model for Series Faults in Low Voltage Microgrids [PDF]
IEEE Transactions on Smart Grid, 2012 This paper presents a dc arc model to simplify the study of a critical issue in dc microgrids: series faults. The model is derived from a hyperbolic approximation of observed arc voltage and current patterns, which permit analyzing the arc in terms of its resistance, power, energy, and quenching condition.
