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.
