Question: In a balance three-phase wye-wye system, the source is an abc-sequence set of voltages. The load voltage on the a phase is VAN = 110

In a balance three-phase wye-wye system, the source is an abc-sequence set of voltages. The load voltage on the a phase is VAN = 110<80o V rms, Z line = 1 + j1.4Ω, and Z load = 10 + j13Ω. Determine the input sequence of the line-to-neutral voltages.
