Radial distribution feeders are characterized by having only one path for power to flow from the source (distribution substation) to each customer. A typical distribution system will consist of one or more distribution substations consisting of one or more “feeders.” Components of the feeder may consist of the following:
- Three-phase primary “main” feeder
- Three-phase, two-phase (“V” phase), and single-phase ...
