A graphic representationof what can be accomplished by using a system of insulated feedersof this sort is shown in Figs. 29, 30, and 31. ioo Technologic Papers of the Bureau of Standards Fig. 29 shows the arrangement of the negative return in whichany feeders that are used are connected directly in parallel withthe track throughout, and a uniform distribution of the load on theline is assumed. The arrows show the direction of the currentflow, and the curved line AB shows how the potentials of the railsvary from point to point, the potential curve becoming steeperand steeper as the power house is approached. With uniformdistribution of the load, as here assumed, and uniform track con-ductivity it can be readily shown that this potential curve is thesegment of
