The verification of a computational model of arc motion using an arc imaging system
The verification of a computational model of arc motion using an arc imaging system
This paper considers the computational modelling of arc motion under short circuit conditions in low voltage circuit breakers with a focus on the verification using controlled experimental conditions. An optical fibre based arc imaging system (AIS) is used to provide the quantitative data on the arc motion. The paper shows that the arc root motion is linked to the arc voltage and that the simulation gives a good representation of the overall arc movement, but is unable to model the high frequency events associated with the arc entry into splitter plates. A modification to the arc model is shown to allow the determination of the exit voltage, prior to arc extinction.

Abstract
This paper considers the computational modelling of arc motion under short circuit conditions in low voltage circuit breakers with a focus on the verification using controlled experimental conditions. An optical fibre based arc imaging system (AIS) is used to provide the quantitative data on the arc motion. The paper shows that the arc root motion is linked to the arc voltage and that the simulation gives a good representation of the overall arc movement, but is unable to model the high frequency events associated with the arc entry into splitter plates. A modification to the arc model is shown to allow the determination of the exit voltage, prior to arc extinction.
