Modelling studies of arcs of short length between copper electrodes: DatasetThe data correspond to the results of modelling studies of DC electric arcs at a current of 2 A in air with admixture of copper metal vapour. Experimental findings are used to adjust input parametrs of the model in order to achieve a good match. The simulations are performed strating with a discharge burning with a minimum gap length of 30 µm for a physical time of 11 ms. Then, the separation of the electrodes is followed for further 51 ms and the discharge gap is increased up to 3 mm. The comparision of experimental and modelling data is based on the measured arc voltage. Variations of the discharge radius during the contact opening, the field enhancement factor, and the molar fraction of copper metal vaopur show the sensitivity of the computed arc voltage.
