r,and 5 volts from center to motors. The motor efficiencymay be assumed at 80 per cent and power factor 80per cent. The E.M.F. at distributing center between themain wires is 205 volts. Determine the wiring as in pre-vious examples. Solution. — For the motors, TX W .725 X 4 X 20 X 746 / =: — —- =… … n in 2 NEUTRAL -o- -o- n -o -o Fig. 43. For the motors, w_ A£ = 270-5x205 = 76>5 KWi 725 For the lamps, $B = ^74-5X205 = KW< y .607 ^=76.5 + 58.9= I3S-4 K.W.The drop will be the equivalent of about 6%. HenceW X D 1200 x 58,900 + 1690 x 76,500 d2 = K 135,400 X 500 i35>4-oo= 396,500 cir.…
