Interconnected System

 Interconnected System 

When the feeder ring is energized by two or more than two source,it is called inter-connected system. 

The single line diagram of interconnected system is shown in figure.

The interconnected system has the following advantages 

It increases the service reliability.

Similarly we can determine the voltage drop for ac distribution system. 

In many cases the load in the system is not concentrated, it may be either uniform loading or a combination of uniform and concentrated loading. 

If the load is uniform then the voltage drop.

Calculated for a very small length of the feeder such as dx and then integrate it over the whole length.
