Series Arc Fault in Low Voltage Electrical Circuits

The paper presents an investigation on electric arc models in order to find a good agreement between simulation and experimental results. Based on the representative models of electrical arc, a simulation in Matlab was performed in order to evaluate the time variation of current and voltage in a circuit affected by an arc fault. An experimental setup was used to visualize the behavior of current and voltage in the series arc within a resistive or inductive circuit. The paper also describes the principle of the newly arc fault detection device and its applicability in low voltage electrical installations.
