Abstract

It may be possible to replace SF₆ gas in power switchgear by exploiting the arc quenching properties of common polymeric materials. In this research, the complex interactions between polymers and arc plasma have been investigated in a realistic environment using a model circuit breaker. The polymers studied were polyethylene and polymethylmethacrylate, which exhibit different processes to quench the arc involving energy removal by melting and secondary reactions respectively.
