Reactance Diagram

With some more additional and simplifying assumptions, the impedance diagram can be simplified further to obtain the corresponding reactance diagram. The following are the assumptions made.

REACTANCE DIAGRAM

 

With some more additional and simplifying assumptions, the impedance diagram can be simplified further to obtain the corresponding reactance diagram. The following are the assumptions made.

 

Additional assumptions:

 

Ø  The resistance is often omitted during the fault analysis. This causes a very negligible error since, resistances are negligible


Ø  Loads are Omitted

 

Ø  Transmission line capacitances are ineffective &

 

Ø  Magnetizing currents of transformers are neglected.

 

Example system

 

as per the assumptions given above and with reference to the system of figure 2 and Figure, the reactance diagram can be obtained as shown in figure
