Electrical arcs and, more generally thermal plasmas, are widely used in many applications
and the understanding or the improvement of the corresponding processes or systems, often …

An accurate and robust method for radiative heat transfer simulation for arc applications was
presented in the previous paper (part I). In this paper a self-consistent mathematical model …

Single-turn coil (STC) is a destructive pulsed magnet aiming at 100–300 T magnetic field.
Due to the high discharge current, the conductor of STC is heated rapidly and undergoes …

The average surface ablation of poly-tetra-fluro-ethylene (PTFE) nozzles in high voltage
circuit-breakers was investigated experimentally by means of the specific ablation …

A switching arc in a model circuit breaker is studied by means of CFD simulations and
optical emission spectroscopy. The arc is initiated between tungsten–copper electrodes in a …

A transient magneto-hydrodynamic model based on@ Ansys-Fluent software applied on a
high-voltage circuit breaker (HVCB) geometry is presented. The model is turbulent (κ-ε …

In high-voltage circuit breakers (HVCBs), the representation of convection is essential to
provide a satisfactory description of the pressure increase in the heating volume or thermal …

A simple integral arc model for ablation arcs in tubes is presented. The model predicts the
arc temperature in the axis, the average electrical field strength, the pressure generation and …

Current interruption is the core technology in low voltage circuit breakers and it is
characterized by the presence of an electric arc. This thesis is an attempt to provide a …

This paper describes an arcing horn device for interrupting the ground-fault current of 77-kV
overhead lines. The main characteristics of the device are as follows. The arcing horn device …
