| Abstract |
IEC 62606-aligned observation windows were used to evaluate 220V, 60Hz series arcs with synchronized three-channel measurements of voltage, current, and UVC. Arc currents of 2.5, 5, 10, and 16A were mapped to windows of 1.00, 0.50, 0.25, and 0.15s, respectively, and each case was repeated five times to compute the number of UVC events exceeding a fixed threshold within the window and the count density ??=??/??. The mean counts were 71.6, 66.0, 71.6, and 72.0, showing near invariance, with coefficients of variation of 5?8%. In contrast, the densities increased monotonically to 71.6, 132, 286.4, and 480s?1. Waveforms confirmed the simultaneous occurrence of current distortion and UVC pulse trains at ignition. Consequently, constant total counts with increasing density was empirically observed, and the clearing-time alignment with a single fixed threshold provides a reproducible benchmark for fair comparison of sensors and algorithms. |
