We study, by optical spectroscopy, the properties of high-current electric arcs that form between opening Cu contacts. The presence of a current that increases linearly with a rate of about 14 kA/ms leads to the separation of the contacts and to the

Investigations of low currents vacuum arcs (< 30 A) have been performed on CuCr, Cu and W contact materials in order to evaluate their chopping current behavior. Results show that the arc burning between CuCr contacts is relatively stable with an ave

We study the impact of Stark line shifts reported recently for Cu I transitions on the radiative cooling of Cu-dominated plasmas. The observed detuning in absorption between the hot core and cold shell of the arc leads to a reduction in radiation rea

The electrode surface temperatures of Cu–Cr butt electrodes exposed to vacuum arcs with sinusoidal currents of 10–20 kA and under external axial magnetic field were determined. Different experimental techniques were applied that can be distinguis

We investigate by time-resolved optical emission spectroscopy the properties of electric arcs forming at the opening of Cu contacts with a current of a few kA. The systematic observation of well-resolved transitions demonstrates that the dense Cu vap

We investigate the temperature-dependence of the light emission properties of Cu-dominated plasmas with pressures in the order of 1 bar and for currents between 0 and 2 kA. While the wavelength of Cu I 3d94s5s transitions for currents above 1 kA is e

Ablation from polymeric casing materials has a pivotal role in switching devices. The ablated gases influence the arc properties and assist the arc movement during current interruption. In this study, spatially resolved optical emission spectroscopy

The optical investigation of arcs in transverse magnetic field (TMF) vacuum interrupters is difficult due to the strong motion of the constricted arc in the magnetic field. In order to determine a first estimate of temperature and pressure distributi
