CONNECTION SCHEMES OF DISTRIBUTION SYSTEM: CONNECTION SCHEMES OF DISTRIBUTION SYSTEM : All distribution of electrical energy is done by constant voltage system. In practice the following distribution circuits are generally used. RADIAL SYSTEM : fig 1.1 In this system separate feeders radiate from a single Bub station and teed the distributors at one end only. Fig.1.1. shows a single line diagram of a radial system for A.C distribution. The radial system is employed only when power is generated at low yoltage and the sub station is located at the centre of the load. Advantages : 1. Simplest distribution circuit 2. Lowest initial cost Disadvantages : 1. The end of the distribu
