In this study, experiments pertaining to direct current (DC) interruptions are performed in an arc‐quenching chamber filled with silica sand. First, the arc column resistance is measured during DC arc‐quenching to demonstrate the elementary aspects of the arc in the silica‐sand‐filled space. Subsequently, an arrangement comprising a polymer cylinder between electrodes in the silica‐sand‐filled space is proposed to increase the arc column resistance during DC arc‐quenching. A polymethyl methacrylate (PMMA) cylinder is used in the experiments. Measurement results indicate that the arrangement of the PMMA cylinder causes the arc column resistance to increase approximately twofold in comparison with the no‐PMMA cylinder arrangement. Finally, the effect of increasing the arc column resistance is discussed in terms of PMMA and silica vapor. © 2021 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.
