Sentence examples for arc duration from inspiring English sources
The arc was driven for an arc duration of 30 μs.
Several arcing faults are simulated, and the effect of harmonics on the fault current and secondary arc duration time is demonstrated.
Compared with the Ag 4wt.% TiB2 contact material consolidated using coarse TiB2 powders, the Ag 4wt.% TiB2 contact material prepared by ultrafine TiB2 powders presents shallower arc erosion pits, larger erosion area, more uniform dispersion and shorter arc duration.
The arc erosion of Ag 4wt.% TiB2 contact materials was tested, the surface morphologies of Ag 4wt.% TiB2 contact materials after arc erosion were characterized by scanning electron microscopy, the spatial distribution of TiB2 particles in Ag matrix was evaluated, and the arc duration and mass loss before and after arc erosion were determined as well.
We have found that all the HAuCl4 molecules will reduce after about 4 min arc duration and in 15 A arc current.
The optical image of as-prepared samples at 15 A arc current and 1 min arc duration, which is pale red, also verifies this result (Figure 4b).
The discharge was between a water-cooled copper cathode (diameter 30 mm) and a thermally isolated anode (diameter 32 mm) with arc currents I=120 225 A, gap distances of h=5 18 mm and arc durations up to 150 s.
But in higher arc durations, the intensity of the plasmonic peak saturates within a few hours.
In lower arc durations, the saturation time was 4 days due to the lower concentration of seeds.
We have examined this common assumption for shorter arc durations such as 30 and even 10 s. Figure 5a,b shows optical absorption spectroscopy of as-prepared samples prepared at 15 A arc current and 30 and 10 s arc durations, respectively.
