Feeder in power system wikipedia.

Feeder protection is defined as the protection of the feeder from the fault so that the power grid continue supply the energy. Feeder is network of conductors which feeds power in different localities from sub station usually at 11kv. An ideal power system needs to control current flow by carefully planning the production absorption and flow of reactive power at all levels in the system. The united kingdom s national transmission system nts is the network of gas pipelines that supply gas to about forty power stations and large industrial users from natural gas terminals situated on the coast and to gas distribution companies that supply commercial and domestic users.

This advantage however is offset by the difficulty of maintaining supply in the event of a fault occurring in the feeder. Many distribution systems operate using a radial feeder system a typical radial feeder system is shown schematically in figure 2. Electric utilities aim to provide service to customers at a specific voltage level for example 220 v or 240 v. In addition to transforming voltage distribution substations also isolate faults in either the transmission or distribution systems.

Transmission line is a network of conductors which transmits generated power from power station to a specific arealies far away from the generating station. The feeders run along streets overhead or underground in some cases and power the distribution transformers at or near the customer premises. Electric power distribution is the final stage in the delivery of electric power. It carries electricity from the transmission system to individual consumers.

In power engineering a feeder line is part of an electric distribution network usually a radial circuit of intermediate voltage. The concept of feeder lines is also important in public transportation. Radial feeders are the simplest and least expensive both to construct and for their protection system. So it is essential to protect the feeder from the various type of fault.

Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kv and 35 kv with the use of transformers. Feeder link a radio link from an earth station at a given location to a space station up link or vice versa down link. An electrical wiring circuit in a building which carries power from a transformer or switch gear to a distribution panel. However due to kirchhoff s laws the voltage magnitude and thus the service voltage to customers will in fact vary along the length of a conductor such as a distribution feeder see electric power distribution.

The term is particularly used in us air travel and rail transport.
