The two stations are electrically connected by a heavy feedersystem, so that under normal conditions during winter months theload of the whole system may be handled from Spring Street sta-tion, using, however, a series booster located 9 miles out on theWesterville line at Minerva Park to maintain voltage on theWesterville end. There is at all times a steady load of considerable magnitude onthe lines running out to the eastern suburbs, and during the sum-mer months on the lines running north to Olentangy Park, apleasure resort which is owned by the company, and which fre- WUTERVILLE LOCATION OF COLUMBUS STATIONS guently attracts large crowds. These loads have continued to in-crease for several years past without making additions to feederlines. Frequently during extreme traffic it has been found neces-sary to use the three M. P. 75-kw machines in parallel as a boosterin order to handle traffic. This overloading of feeders has occa-sioned heavy loss in transmission. In order to determine just ex-actly what this average loss is, two wattmeters were calibratedtogether; one was then installed in the feeder line at the powerstation, the other where the feeder taps into the trolley—the dif-ference in watts showing exactly the loss resulting in transmission,both in overhead copper and ground return. These meters havebeen installed for two weeks at a time under average conditions inoutlying feeders which would be afifected by the installation of analternating system. The results show the loss to be equivalent tothe following per cent of t
