Componets on a power 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.. . It is a common knowledge that electric power is almost exclusively generated, transmitted and distributed as AC However, for certain. . A considerable amount of effort is necessary to maintain an electric power supply within the requirements of various types of consumers.. . The voltage drop in distribution system is calculated by following Ohm,s Law. Let us consider a simple do radial distribution system as shown in Figure 9. The system have concentrated. [pdf]
