The single line diagram of a power system is the network which shows the main connections and arrangement of the system components along with their data (such as output rating, voltage, resistance and reactance, etc. ) .  \nCircuit breakers are represented by rectangular blocks. It is difficult to draw the line diagram of the few components. So for simplification, the impedance diagram is used for representing the power system components.  \nSingle Line diagram of an Electrical system  \nTwo generators one grounded through a reactor and one through a resister connected to a bus and through a step up transformer to a transmission lines.
