My question is regarding the simple arrangement below: enter image description here

It is simply a three phase source feeding a load through Z1, followed by an ideal WYE DELTA transformer, followed by Z2.

My question is how do I refer the impedance Z2 to the left hand side?

  • \$\begingroup\$ It depends on what Z2 connects to and your drawing doesn't show that. \$\endgroup\$ – Andy aka Oct 5 '18 at 7:32
  • \$\begingroup\$ Z2 connects to a three phase load \$\endgroup\$ – CKCK Oct 5 '18 at 8:14
  • \$\begingroup\$ 3 phase impedance transfer functions are easily found on the web. Have you tried? \$\endgroup\$ – Sunnyskyguy EE75 Oct 6 '18 at 19:05
  • \$\begingroup\$ @TonyEErocketscientist Im not looking for a transfer function, Im just looking how to simply refer the impedance to from the secondary side to the primary side. \$\endgroup\$ – CKCK Oct 7 '18 at 23:23
