EXCITERS Both steam-driven and motor-driven exciter sets are in-stalled. The steam-driven set is located near the housepumps and consists of a horizontal Curtis steam turbinewith a speed of 2400 r. p. m, and a G. E. 125-volt, 75-kwgenerator. The motor-driven exciter set consists of asimilar generator driven by a three-phase, 2080-volt in-duction motor. AUXILIARY STEAM PIPINGSteam for the wet and dry vacuum pumps and the oilpumps

AUXILIARY STEAM PIPINGSteam for the wet and dry vacuum pumps and the oilpumps of each turbine is supplied from the main headersupplying the turbine. The two house pumps and circulat-ing water pumps get their steam from the header of turbine. SWITCHBOARD AND ELECTRICAL APPARATUSThe switchboard is installed on the turbine rpom floor operating room by one small door. The generator leads,consisting of 700,000-circ-mil. paper-insulated, lead-cov-ered cable, pass directly to banks of 750-kw oil-insulated.
