Those for the large unitsare 12 ins. x 18 ins., and the one for the smaller unit is 10 ins. x14 ins. x 18 ins. Between each engine and condenser is placedan automatic three-way exhaust relief valve, so connected thatin case of a break in the vacuum, the exhaust is thrown auto-matically to the atmosphere, and the passage to the condenserclosed, thus preventing the possibility of the water from the con-denser backing up into the exhaust pipe of the engine, without theintervention of an additional gate valve. After the condenser isagain started the valve may easily be thrown over to the other. LAYOUT OF POWER HOUSE position, when the vacuum will firmly hold it. The condensersdraw from a 14-in. suction line in common, and discharge alsothrough a common line, these being located in the boiler roombasement before mentioned. Pockets are provided in the dis-charge lines, from which the heater is supplied as before outlined. The electrical equipment consists of two 540-kw and one 360-kwrevolving field type, three-phase, 25-cycle, 13,000-volt generators;two 17-kw exciters running at 125 r. p. m., and one 15-kw ex-citer running at 150 r. p. m., each directly connected to the shaftof its respective generator; one 360-kw rotary converter, and four110-kw oil cooled transformers. The 13,000-volt cables runningfrom the generators are carried directly to the oil switches inthe oil switch room, which is located in the engine room directlyback of the switchboard, as shown in the cut. All transformers,lightning arresters and automatic overload devices are cont
