DISTRIBUTION SYSTEMS

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 […]
