Another Westinghouse 1500 machine has been installedin the Thirty-third and Market Street power house of the UnionTraction Company, and a second one of the same size is nowbeing constructed. In addition to these six 1500 machinesthe Union Traction Company also has in operation three four-pole Kodak and five Westinghouseengine type generators distributed among their several powerhouses. Fig. 7 shows one of four 800 , 650-volt Westinghouse en-gine type generators installed in the power house of the Southside Elevated Railroad, Chicago. They each have ten poles and. FIG. 5.—ARMATURE FOR 800 ENGINE TYPEGENERATOR are direct connected to Allis cross-compound condensing Corlissengines running at 80 The performance of these machinesis shown by the curves in Fig. 8. The field winding is so designedthat the voltage will rise from 600 volts at no load to 650 at fullload, as shown by the regulation curve. It will be noted thatfrom a load of 800 amps, to full load, which is 1230 amps., theefficiency is over Q\V2 per cent, while even at quarter load it isover 90 per cent. These machines are capable of generating con-tinuously 1230 amps, at 650 volts, and will operate for three hoursat 50 per cent over load with a rise of temperature not exceeding30 deg. C. above the temperature of the surrounding air.
