1 Problem Set #8 The symmetrical components of unsymmetrical phasors 8-1 (Keyhani Lecture) Given = Z Z Z Z abc 0 0 0 0 0 0 Find Z 012 . 8-2 (Keyhani Lecture) Consider the circuit shown below. Suppose V an =100 0 ° , V bn =50 180 ° , V cn =50 180 ° , Z s =8+ j 10, and Z ab = Z bc = Z ca = j 4. a) Calculate I a , I b , and I c without using symmetrical components. b) Calculate I a , I b , and I c using symmetrical components. 8-3 (Keyhani Lecture) Frequently, T is defined as 2 2 1 1 1 1 1 3 1 a a a a When this is the case, T is unitary. a) Prove it. A matrix is unitary when its inverse equals its transpose conjugate.
