Radial System

 Radial System

In this system, separate feeders radiate from a single substation and feed the distributors at one end only. 

A single line diagram of a radial distribution system is shown in Fig. 

The radial system is employed at low voltage and the substation is located at the center of the load.

This is the simplest distribution circuit and has the lowest initial cost. 

The end of the distributor nearest to the feeding point will be heavily loaded.

The consumers are dependent on a single feeder and single distributor. 

Therefore,any fault on the feeder or distributor cuts off supply to the consumers. 

Who are on the side of the fault away from the substation.

The consumers at the distant end of the distributor would be subjected to serious voltage fluctuations when the load on the distributor changes. 

Due to these limitations, this system is used for short distances only. 

The radial system can be extended by introducing more laterals and sub-laterals.
