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.
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.
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
