GENERATORSConnected to each steam turbine bymeans of a sleeve coupling is a 750-kw,3300/6600-volt, three-phase, 25-cyclewestinghouse alternator of the revolv-ing field type. The armatures are star-connected so that single-phase currentcan be taken from any two advantage of this type of windingis that a small amount of polyphasepower can be secured at the same timethat single-pha
