摘要：
Current zero measurements in modern circuit-breakers are presented: vacuum interrupters always exhibit post-arc current when breaking at high current. On the other hand it is shown that, due to the very short time constant of SF6 circuit breakers, no measurable post-arc current is driven in these devices. A description of the current zero phenomena in SF6 is proposed, which includes the interaction with the circuit.
