This transmission starts from the LStreet station of the Edison Company on the water front in SouthBoston and extends to eighteen cities and towns, some of which arefully 25 miles distant. This transmission has been made possible through the purchase bythe Edison Company of the electric generating stations and systemsin Woburn, Somerville, Watertown, Needham, Dedham, Milton,Dover, Canton, Natick and Framingham. The operation of these.

Thecircuits that now connect the L Street station with the most distantsub-stations of the system are thought to insure moderate trans-mission losses and good regulation, but when the loads at thesedistant sub-stations have increased, the transmission voltage at thegenerating plant may be raised to 13,500 by transformers. At the various sub-stations connected to these 6,900-volt trans-mission circuits the line current goes either to static transformersor to motor-generators. The motors of these generating sets arethree-phase, 60-cycle machines and receive the 6,900-volt current inthe
