Not illustrated. 1907 Excerpt: ...injector to supplement the pumps. From the boilers the steam from each battery passes to its turbine through 12-inch mains with cross-connections for emergency use. From the turbines the steam goes to surface condensers supplied with water by centrifugal pumps located in the adjacent pump house. The condensed steam and air are exhausted from the condensers by air pumps which deliver the water to the hot well, thus completing the steam circuit. The alternators are 12-pole, 60-cycle, three-phase, 4600-volt F1g. 117. Section of the power plant of the Long Island R. R. Co., illustrating horizo1 tal steam turbine practice (this figure and Nos. 118 to 121 are from the St. Ry. Jour.). machines and they operate at 600 r. p. m. They are furnished with field current by two exciters of 50-k. w. capacity each, direct connected to 75-horsepower three-phase induction motors. The exciters are supplemented by a storage battery of a capacity of 556 amperes discharge for one hour. While this is primarily a lighting plant, a certain amount of power is furnished to the local railway company from a substation located in the turbine room. It contains a 1ooo-k. w. motor-generator set supplemented by a motor-generator booster set consisting of a 300-volt, 450-ampere generator driven by a 500 volt motor. From the generators the current passes to oil-immersed generator and feeder switches controlled from a switch board and located in galleries at the side of the turbine room. The power is distributed to substations in which are located transformers, synchronous motor-generator sets, induction motor-generator sets, storage batteries and other apparatus to adapt the output to the demands of different localities. A large part of the lighting and motor service on the system is direct cu...
