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 …

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 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 …

In order to investigate the influence of the electrode separation, arc time and frequency of
the reverse current on the breaking capacity of vacuum breakers in a DC interrupting …

It is well known that vacuum circuit breakers (VCB) have such superior characteristics as
small size, light weight, small noise, frequent interruption, easy maintenance, and no …

The recovery characteristics of the withstanding voltage of a vacuum gap are crucial for the
development of direct circuit breakers with mechanical switches. In the active-current …

A high‐speed vacuum circuit breaker (HSVCB) has been investigated. HSVCB makes high‐
frequency current superimposed on a fault current so that the current is forced to be zero and …

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 …

The authors have investigated a high-speed vacuum circuit breaker, which forced a fault
current to zero. A high frequency current was superimposed on a vacuum interrupter so that …
