Arcs in gas circuit breakers have been regarded as resistances when a zero-miss current
interruption phenomenon has been simulated by a computer. However, the model involved …

This paper discusses the analysis of arc conductance in a gas circuit breaker (GCB) during
current interruption process and the investigation method of the interruption capability. There …

This paper shows the simulations of SLF interrup-tion performance for SF6 gas circuit
breaker by serially connected 3 arc models. The arc model is constructed by serially …

SF6 is exclusively used as insulation and quenching medium for high voltage circuit breaker
because of its high insulation strength and high interruption capability of fault current at …

Mayr-type arc equations were applied to the analysis of high frequency arc extinctions in
SF/sub 6/gas blast circuit breakers. Parameters for the arc equations were obtained from the …

The arc behavior in the current zero region is critical in the case of very steep rising TRV,
such as after clearing a short-line fault. Therefore, intensive and abundant short-line fault …

A detailed dynamic arc model may be used to roughly evaluate the interrupting capacity of a
breaker and its influence on the deformation of the interrupted current. In some cases the …

This paper covers the derivations of a hyperbolic partial differential equation for the dynamic
arc radius in a circuit breaker nozzle. Starting at peak current, this equation is solved for a …

In recent years some work has been conducted in the area of circuit breakers modeling in
order to improve the capability of high voltage circuit breakers through simulations. Most of …

CFD (computational fluid dynamics) calculations for high-and low-current arcs in an
interrupter of the self-blast type have been performed. The high-current simulation provides …
