Measurements and modeling in the current zero region of vacuum circuit breakers for high current interruption

Post-arc current and voltage measurements with high time resolution were carried out with industrial vacuum circuit breakers for investigating their current zero conditions and current interruption. Based on experimental results, plasma parameters were estimated by means of a modified "continuo...

Zusammenfassung:Post-arc current and voltage measurements with high time resolution were carried out with industrial vacuum circuit breakers for investigating their current zero conditions and current interruption. Based on experimental results, plasma parameters were estimated by means of a modified "continuous transition model." Dielectric effects in the post-arc current zero region were detected and modeled. At lower current amplitudes (I/spl circ/
