A hydrodynamic model for electrical arc modelling, which takes into account Joule heating, radiation, Lorentz forces, arc - wall interactions and real-gas effects, was applied to study high-, medium- and low-voltage circuit breakers. The first indust

A sustained current conduction in the breaking chamber after a current interruption has been observed. This current, which we named 'Post-recovery (PR) current', is in phase with the applied voltage and its value ranges from several milliamps up to s

Modeling of gas movements in a circuit breaker arc chamber requires an accurate knowledge of thermodynamic functions. The proposed method gives a simplified form of the law of state, in close agreement with the tables. This law has been implemented i

A novel post-arc current measuring shunt is described. This shunt employs parallel connected diodes to automatically insert and disconnect the measurement resistance, very close to the current zero. The realized precision and sensitivity allow reprod

Summary form only given. When an electrical arc is initiated between contacts, light radiation is a typical arc manifestation. This radiation is absorbed in different ways by the surrounding gas. After the hot region of the arc, this radiation propag

The effects of adding cooling fins to an auto-expansion circuit-breaker chamber are investigated. It is found that they reduce considerably the post-recovery current. An indirect effect of the reduction in dissipated energy on arc voltage further inc

This paper presents a study of instabilities and of spontaneous extinctions which occur in low current dc arcs between metal electrodes. A theoretical model for the behavior of emitting sites on the cathode surface is proposed. This model explains ex
