NT—OIL SWITCH AND BUSBAR COMPARTMENTS ON MIDDLE GALLERY ALTERNATING-CURRENT AND DIRECT-CURRENT OPERATING PANELS ON TOP GALLERY IN TURBINE ROOM 864 ELECTRIC RAILWAY JOURNAL [Vol. XLIX, No. 19 are of the GE-H3 type. This arrangement providesvery simple high-tension wiring on these two galleries. The uppermost gallery contains the switchboard andhorn gaps and electrolytic lightning arresters for an11,000-volt alternating current circuit, and from it alsothe direct current feeders pass through bushed holes inthe wall to the overhead line. The switchboard is soplaced as to command a view of the entire turbine roomand it is conveniently reached by the bridge from theturbine walkway. The electrical features of the plant are summarized inthe accompanying circuit diagram. On this it will benoted that, in addition to the items already mentioned,there is double provision for excitation from a set and a 200-kw. motor set.
