Distribution System Connection

Distribution System Connection: All Distribution System Connection of electrical energy is done by constant voltage system. In practice, the following distribution circuits are generally used 1.Radial System: In this system, separate feeders radiate from a single substation and feed the distributors at one end only. Fig. 12.8 (i) shows a single line diagram of a …

Overhead vs Underground System

Overhead vs Underground System: The distribution system can be Overhead vs Underground System. Overhead lines are generally mounted on wooden, concrete or steel poles which are arranged to carry distribution transformers in addition to the conductors. The underground system uses conduits, cables and manholes under the surface of streets and sidewalks. The choice between Overhead …

DC Distribution System

DC Distribution System: It is a common knowledge that electric power is almost exclusively generated, transmitted and dis­tributed as a.c. However, for certain applications, d.c. supply is absolutely necessary. For instance, d.c. supply is required for the operation of variable speed machinery (i.e., d.c. motors), for electro­chemical work and for congested areas where storage battery …

AC Distribution System

AC Distribution System: Now-a-days electrical energy is generated, transmitted and distributed in the form of alternating current. One important reason for the widespread use of alternating current in preference to direct current is the fact that alternating voltage can be conveniently changed in magnitude by means of a transformer. Transformer has made it possible to …

Electric Power Distribution System

Electric Power Distribution System: Electric Power Distribution System states that part of power system which distributes elec­tric power for local use is known as distribution system. The electrical energy produced at the generating station is conveyed to the consumers through a network of transmission and distribution systems. It is often difficult to draw a line …
