Voltage-time curves and performance functions of composite insulators for MV overhead line stressed by short tail impulsesThe withstand voltage of an insulator subjected to lightning direct or induced overvoltages is checked using standard and non-standard (short tailed) lightning impulse.Ileana Baran...
The paper constitutes a systematic theoretical and experimental investigation into impulse breakdown voltage time curves of coaxial-cylinder gaps in SF6 and a 50% SF6-50% N2 mixture. The breakdown time delay probability is treated as a bivariate distribution in statistical and formative time lags. A...
aTypical curves relating the critical flashover voltage and time to breakdown for rod gaps of different spacings are shown in Figure 10.10. 关系重要闪络电压和时期与故障为不同的间距标尺空白的典型的曲线在表10.10显示。[translate]
The curves obtained by Noda et al. as well as Taniguchi virtually overlap with that by theoretical calculation, indicating that the distribution line can be modelled by both methods appropriately in electromagnetic analyses. When the wire radius is between 0.15Δr and 0.65Δr, these models have ...
The evolutions of the IC curves of the tested LFP and NCA batteries are plotted in Fig. 19. As can be seen, the area under the third peak for the LFP battery, i.e., Peak3,LFP, and the area under the second peak for the NCA battery, i.e., Peak2,NCA, gradually reduce with ...
Comparison of receiver operating characteristic curves confirmed that the superior performance of the horizontal plane time-voltage integral relative to standard and other signal-averaged criteria was independent of partition value selection. Conclusions. These findings suggest that use of the time-voltage ...
The voltage dip of the designed system is assessed by the pre- and post-system average root mean square (RMS) variation frequency index, and the voltage dip index is compared with the Information Technology Industry Council (ITIC) curves. The simulation results demonstrate that the inverse-time ...
5 % sodium chloride solution were observed and the corrosion rate, time-voltage curve and Tafel polarization curves were determined. 5%NaCl溶液中腐蚀后的表面形貌,测试了腐蚀速率、时间-电位曲线和塔菲尔极化曲线。2) potential-time curve 电位-时间曲线3...
The distributions of time to progression to AD were estimated for each tertile using cumulative incidence curves and compared statistically using a log-rank ... CI Prodan,ED Ross,JA Stoner,... - 《Neurology》 被引量: 42发表: 2011年 On the impact of hardware faults --- an investigation of...
It is found that, when a runaway electron beam is generated and voltage pulses have a subnano-second rise time, the breakdown voltage rises as the nitrogen pressure decreases from 9 × 10 to 1 × 10 Pa. Experimental data are in good agreement with pulsed breakdown analytical curves. 展开 ...
