Automatic control for a high tension arc furnace (1917)
Bagley, Glen David · leaf 28
Figure 2. in C is thenYT times 98 cimperes, or 170 amperes. Resis- tances and R^ are gg or 2.22 ohms and are divided into two equal parts. The arc resistance, however, is introducedin all three lines approximately equally as the electrodesin all three phases are separated simultaneously. Then… … // y no \V t A 0 3 Figure 3. Figure 4. By trial, it was found that the resistance ofthe arcs would have to rise to 0.5 ohms in order to reducethe current in lines A and B from 98 amperes to 65 amperes.At this point the first contactor cuts out half of theseries resistance, reducing it from 2.22 to…
