3.6. Distribution Systems
Oftenly it is impossible to draw a line between the distribution and transmission systems of a large power network. In general, distribution systems comprise that part of the network of a power system which distributes power for local use.
Distribution systems may be classified as follows:
1. Nature of current:
- Direct current
- i. Two wire
- ii. Three wire
- Alternating current.
2. Method of connections:
- a. Series
- i. Open loop
- ii. Parallel loop
- iii. Combination of open and parallel loops
- b. Multiple
- i. Three system
- ii. Feeder and main
- iii. Network
- iv. Loop system
- v. Ring system.
- c. Number of phases:
- i. Single
- Two wire
- Three wire
- ii. Two
- Three wire
- Four wire
- Five wire
- i. Three
- Three wire
- Four wire
- i. Single
- d. Mounting:
- i. Overhead
- ii. Underground
Voltage: 115/230,550, 1100,2200,6600, 11000, 12000,13200,32000 V.
