CTRIC TRANSMISSION OF ENERGY. margin of load on the motor. In the present case thebreaking-down load corresponds to a supply of 157 Kwt.Since 7 Kwt. is required for excitation and to overcomelosses in the motor, 150 Kwt. or about 200 horse-power isthe maximum that can be given off. The normal… … output. It would scarcely be safe to rely on a trans-mission plant which is only capable of carrying 60 percent, excess load. To increase the margin of safety wemust excite the motor to a higher degree. Fig. 96shows the power curve if the motor is excited with15,000 ampere turns, giving an E.M.F.…
