- Positive Sequence network:
- For any given condition(sub-transient, transient or steady state), draw the per unit reactance diagram, which will represents the positive sequence network
- Negative sequence network:
- Determine the per unit negative sequence impedances of all elements
- If the value of the negative sequence is not mentioned for any element, it can be approximately consider as equal to positive sequence impedance
- Zero Sequence network:
- Draw the zero sequence network corresponding to the grounding conditions of different elements of the power system.
- Mention all the impedances by its zero sequence values.
