These transformers onboth primary and secondary windings are arranged for cutting inor out coils or sections for voltage adjustment Two 300-kw, rotary converters are installed in the power house,for handling the sections of the line adjacent to the power house.Ih. rotaries are Started by an induction motor direct connected tothe armature shaft, and synchronized by means of lamps connectedon one side to bus bars and on the other to tin. alternating currentside of the rotaries. The switch controlling the starting motor isof the double throw type, arranged fur high ami low volta.nections to transformers. Consequently, with one position of theswitch the motor develops a speed -lightly in excess of the syn-chronous speed and with the other position, a speed below it. Thispermits of the proper speed being reached as indicated by the syn-chronizing lamps. Each governor arm of the 750 h. p. engine, driving the alternator. VWV VVW WW pyj^r^

DIAGRAM OF STATION WIRING. One exciter panel (two exciters). 2 alternator panels, 2 transform.cr panels, 2 alternating current rotary panels, 2 direct current ro-tary panels, I direct current trolley double feeder panel. This switchboard is of the Westinghouse standard pattern. Theprincipal features of the boards are a totalizing, integrating watt-meter, placed on each alternator panel; a double, low tension busbar arrangement for flexible manipulation of alternators with trans-formers and rotary converters, and separate ammeters for eachphase reading to 1200 amperes. Synchronizing lamps and shunt transformers are used, when ma-chines are to be synchronized with bus bars. The step-up static transformers, which are located in a gallery,are of the Westinghouse oil cooled type, and are seven in number(two sets of these each and one spare), each being of 200 kw. ca-pacity. The ratio of conversion is one to fifty. Two fuse cut-outsare placed on the low tension, or machine side of each tran
