A Holly gravity drip system is also in use,and the condensers are of Wheeler admiralty design, surfacetype. The Post Street station supplies current at three 500-kwWestinghouse 6o-cycle, two-phase, 360 r. p. m., 250-volt direct-connected rotary converters for power and lighting service,and also to five 500-kw Westinghouse railway rotaries, running400 r. p. m., three-phase at 550 volts full load.
