Electrical Power Distribution Diagram

Central station where power is generated by 3 phase alternators.

Electrical power distribution diagram. The riser diagram is the illustration of the physical layout of electrical distribution in a multilevel building using a single line. Primary distribution lines carry this medium voltage power to. Between the generating stations and the distribution stations three different levels of voltage transmission sub transmission and distribution level of voltage are used. Figure 12 schematic of a car s electrical circuit.

In figure 1 c s. Electric power is transferred by from primary distribution line i e 11kv to distribution sub station is known as secondary distribution. Figure 10 comparison of an electrical schematic and a wiring diagram. As you are into the workspace of edrawmax drag the symbol that you need directly onto the canvas.

When dealing with a large power distribution system a special type of schematic diagram called an electrical single line is used to show all or part of the system. Figure 11 wiring diagram of a car s electrical circuit. This sub station is located near by domestic consumers areas where the level of voltage reduced to 440v by step down transformers. Figure 1 a typical electric power distribution system.

Substations transform voltage from high to low or the reverse or perform any of several other important functions.

The distribution of electric power to different consumers is done with a much lower voltage level compared to the transmission of power over long distances i e.

Represents the central station where power is generated by 3 phase alternators at 6 6kv or 11kv or 13 2kv or even 32 kv. It carries electricity from the transmission system to individual consumers. Basically we can say that part of power system which distributes electric power for local use is known as distribution system. Electric power distribution is the final stage in the delivery of electric power.

It shows the size of conduits wire size circuit breaker rating and other electrical devices rating of switches plugs outlets etc from the point of entry up to the small circuit branches on each level. Over long transmission lines. Between the generating station and consumer electric power may flow through several substations at different voltage levels. Electrical power distribution system.

The main function of an electrical power distribution system is to provide power to individual consumer premises. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kv and 35 kv with the use of transformers. Single line diagram of power supply system the electrical energy is produced at generating stations and through the transmission network it is transmitted to the consumers.
