When the contacts of a circuit breaker are opened just before the current zero, the gap
between the contacts after the current interruption will still be very short. Therefore, it cannot …

When the contacts of circuit breaker are opened just before current zero, the gap between
contacts will still be very short. Therefore, it cannot withstand recovery voltage between the …

Re-ignition during short circuit interruption process is one of the most important phenomena
circuit breaker design engineers have to deal with. It has direct impact on short circuit …

Post-arc current significantly influences the interrupting process of breakers, which can
reflect the appearance of the arc before current zero and the residual metal vapors in …

When inductive load is interrupted by VCB, extinction and re-ignition may be observed
repeatedly by balance with recovery voltage. This is due to high frequency current …

The contact morphology change caused by high-current ablation will seriously affect the
electric field distribution in the interrupter chamber, which in turn affects the closing …

It is significant for circuit breakers to expel a short-circuit fault in a short time for the new
power grid with high proportional photovoltaic or wind power plants to achieve high transient …

When 40.5 kV vacuum circuit breakers are used to break currents in distribution system,
reignition phenomena occur frequently resulting in high overvoltage and even interruption …

Dielectric recovery after arc extinguishes in vacuum circuit breaker is very fast, the arc
current may be cut off before natural current zero. In order to study the current zero period …

The self-blast type circuit breaker has been developed to reduce mechanical operation
energy by building up the pressure of arc extinguishing gas flow from the heat of the arc …
