Influence of polymer plates, made from Al2O3, PE (polyethylene), POM (polyoxymethylene), PBS (polybutylenesuccinate), PA66 (polyamide 66) installed in the vicinity of arc column, on arc properties was investigated experimentally. Arc voltage initiated between the parallel polymer plates were measured in the range of several kA. In addition, composition of gas ablated from the polymer plates during the current interruption was analyzed. Current interruption experiment for gas analysis was carried out in the sampling bag backfilled with N2 to distinguish the ablated gas from the gas included in the air. It was found that the major composition of ablated gas was H2 and CO.
