After pass-ing through the bearings it descends to the basement, fromwhich point it is filtered, and is then pumped back to thetank. An automatic arrangement is provided by whichif there is any lack of oil supply in the tank a whistle isblown in the engine room. The generators are of the standard Westinefhouse rail-. VIEW OF POWER STATION way type, with a nominal capacity of 1460 amps., and ac-tual capacity of considerably more under different condi-tions, as mentioned later. The generators run at 82 no load, and give then 500 volts. At nominal load, Cent, in any part of the machine; and also to carry 2560amps., which is 75 per cent overload, with not less than550 volts for a short period. The commercial efficiencyof the machine at one-fourth load is 90 per cent; one-halfload, 92 per cent; three-fourths load, 93 per cent, and fullload, 94 per cent. The output of the machine at differentrates of loading is shown diagramatically in the accom-panying data curves. The ma-chine is also guaranteed to produceno sparking within the limits of noload and 50 per cent overload, orto require any shifting of brushesbetween these limits. It is alsoguaranteed not to buck at theopening of the circuit breaker at2500 amps. The machine is testedbefore leaving the works to standan alternating e.
