f full loadcurrent. Each step should be zirT jthe effective resis-tance of the furnace arcs. The computations for reactanceinstead of resistance are similar except that the value ofthe reactance drop is at right angles to the load currentinstead of in phase with it. The furnace transformer used in… … J Z1 ^ 18 amperes./.3 to keep the starting current down to one and one-half timesfull load current or 08 amperes in each phase as explainedabove. The leg voltace is 127 as shown in Figure 1, The value of the aeries resistanceis then ^^oT ^^ oliras.This is divided into two stepsof .65 ohm each. The…
