Parallel feeders. Ring main. Meshed systems. 1. Radial. Many distribution systems operate using a radial feeder system. A typical radial feeder system is shown schematically in Figure 2. Radial feeders are the simplest and least expensive, both to construct and for their protection system. This advantage however is offset by the difficulty of ...The electric feeder is equipped with a special protective device that protects against overloads and short circuits thanks to the availability of circuit breakers. These switches disconnect the contact network if an over-protection occurs. A high voltage disconnector can do this.
