Wire impedance
Wire impedance
(OP)
II need to calculate the impedance for 3-1/c #1/0 RW90 wires in steel conduit. This is the secondary of 240V single phase transformer. I have the values for 3-1/c wires and somebody told me that for 2 wire the impedance will double!
I can’t find any reference to this to back it up and he says it’s based on experience. Any idea how I can calculate this.
Thank you

RE: Wire impedance
For three phase applications, the current in the return conductor is reducced to be zero for balance conditions with not significant harmonics.
RE: Wire impedance
As I mentioned, transformer secondary is 120/240v.
I am not sure if SKM will consider this automatically or I need to pt two cables inseries to double up impedance?
