The transmission loss is, of course, muchgreater with the 3-wire system than with the transformersystem; but, on the other hand, the combined losses inthe converters and the transformers is greater than thecombined losses of the compensators and the neutral wireof the 3-wire system. The relative economies of the twosystems are as a whole (Fig. 11) largely in favor of thetransformer system, and Mr. Parshalls plans were finally Starting from the generating station, the average trans-mission loss in the first section will be put per cent, inthe second section per cent, and in the third section per cent. The total lossesof all kinds in the cables willamount to but per cent. From an inspection of thevoltage curves on the third andtrack rails, shown in Fig. 12, itwill be seen how small a drop isintended, and how well the trans-former system lends itself to theequalization of pressure over anextended line.
