vol-tages at full load reach 4,100for each circuit on the 100-lightmachine. The second system, usedfor series distribution onalternating-current circuitsconsists of a constant-potentialtransformer, stepping down theline voltage to that requiredfor the total number of lampson the system, allowing… … Fig. 47.
