POWER DISTRIBUTION 

The distribution system begins after the Main Substations. Its transmission components may be divided into 3 parts: 

Feeders
Distributors
Service Mains 

Feeders              =>  Conductors which connects the Main Substations to 
                               the various distribution substations. There is no 
                               tapping from the feeders.
                               In other words, the current loading of a feeder is 
                               the same along its entire length.

  Distributors        => Conductors that radiate out from distribution 
                               substations to their allotted consumer areas. 
                               Various tappings are taken from the Distributors. 
                               Hence, a distributor has distributed current loading  
                               along its entire length.

  Service Mains      => The connecting links between the distributor and 
                               the consumer terminals.
