3. (a) (i) State four assumptions made in the analysis of unsymmetrical faults. The system is linear*. The system is balanced* prior to the fault. The impedances of the system are symmetrical* (i.e., self-impedances of phases are equal, and mutual impedances between phases are equal). The generated EMFs are balanced* and sinusoidal. 3. (a) (ii) Define "operator a" as used in symmetrical components theory. The operator a is a complex number that represents a counter-clockwise phase rotation of 120^. It is defined as $a = 1 120^ = e^j
