The dataset contains series arc faults voltage and current signatures in a DC low power network. The first apparatus performs a series arc fault by opening contacts (ReadMe_test 1). After breaking, copper electrodes are maintained at a constant gap. The measurements are performed with direct current and resisve/Inductive loads. The second apparatus performs contact breaking under chosen voltage and current supply condions (ReadMe_test2). After breaking, electrodes are maintained at a constant gap during electrical measurement. The measurements are performed with direct current and resisve loads by separating electrodes.
