UNIT IV FAULT ANALYSIS – UNBALANCED FAULTS 9
Introduction to symmetrical components – sequence impedances – sequence circuits of synchronous
machine, transformer and transmission lines - sequence networks analysis of single line to ground,
line to line and double line to ground faults using Thevenin’s theorem and Z-bus matrix.
