Feeding Point. In order to determine the point at which asystem of mains should preferably be fed, that is, the point where 25 16 POWER TRANSMISSION the feeders are attached to the mains, it is necessary to find theelectrical center of gravity of the system. The method employedis similar to that used in determining the best location of a powerplant as regards amount of copper required, and consists of sepa-rately obtaining the center of gravity of straight sections and thendetermining the total resultant and point of application of thisresultant of the straight sections to locate the best point for feed-ing. Actual conditions are often such that the system cannot be.
