If positive-sequence voltages are assumed and the
Chapter , Problem 3.31(choose chapter or problem)
If positive-sequence voltages are assumed and the wye-delta connection is considered, again with ideal transformers as in 3.29, find the complex voltage gain C3. (a) What would the gain be for a negative-sequence set? (b) Comment on the complex power gain. (c) When terminated in a symmetric wye-connected load, find the referred impedance Z0L, the secondary impedance ZL referred to primary (i.e., the per-phase driving-point impedance on the primary side), in terms of ZL and the complex voltage gain C.
