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 …

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 …

Interrupting frequency has a great influence on the breaking capacity of the breakers. In this
paper, using the forced current zero method, vacuum DC interruptions were carried out in …

The paper established the simulation model of series vacuum arc of Vacuum Circuit Breaker
(VCB) with double-break using Magneto Hydro Dynamic (MHD) model. To gain the …

With a capacity increase of the power system, the fault current increases very quick and it
becomes a threat for other equipment in the power system. Vacuum interrupter combined …

The repeated breakdown of vacuum circuit breaker during the breaking process causes
overvoltage and intensifies the insulation deterioration of high-voltage equipment. The work …

Vacuum interrupters are serving worldwide in distribution circuits, meeting the electrical and
mechanical requirements specified in the IEC and/or ANSI standards for low and medium …

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 …

In the present work, influence of the beginning of the contact opening of the vacuum circuit
breaker on the main characteristics of the discharge and the breaking capacity of the …

The restrike of vacuum circuit breaker during the breaking process causes overvoltage and
intensifies the insulation deterioration of high‐voltage equipment. To solve this problem, the …
