The diagram shows the Cos Cob power station, whichcontains 11,000-volt three-phase generators, used single-phase for the railroad electrification but three-phasefor the other power transmission. By means of auto-transformers installed at the power house connected asshown the voltage is raised to 22,000, and the middlepoints of the transformers are connected to the auto-transformers are arranged along the track.
