Electrode burn-off

Figure 6.156 Copper electrode burn-off versus arcing time t for short-circuit currents in the range 0.8kA. ..15kA rms. Figure 6.156 Copper electrode burn-off versus arcing time t for short-circuit currents in the range 0.8kA. ..15kA rms.
For copper, the electrode burn-off versus arcing time has been measured for different short-circuit currents up to 15 kA (root mean square value), see Fig. 6.156. [Pg.317]
