It is deriveil from two exciter units, each of whichconsists of a Wcstinghoiise single acting compound engine, runningat a speed of 275 r. p. ni,. direct coupled to a loo-kw. 125-volt coni- coiivcyom, etc. These motors arc operated from a special three- phase, 440-voll engine-driven generating set of loo-kw. capacity. As an alternative source of power for this purpose, four so-kw. transformers arc nistalled, connected through oil switches to the high tension s«ilchlx)ard bns-hars. The condensing plant is of the harometric type and was made bythe Dritisli VVeslinghonse (o at the 1 rafTord Iarkworks, accoriling to the designs of the .Mhcrger Con-denser Co. Condensers are nistalled for maingenerating unit, and they are separately capable of dcal-nig with ) Ih. of steam per hour at normal fid
