I can't remember whether the qu mentioned if 0.23 was the measured live conductors resistance (ie R1+RN). I myself, didn't use any correction factors, but can see why people have. I thought the that 1.2 correction factor was for correcting the R1+R2 part of the Zs=Ze+(R1+R2) equation, as its carried out as a dead test, and therefore the conductors aren't at operating temperature? But thinking about it... The same logic could be applied to an R1+RN test?
It mentioned that it was the total measured resistance of R1 and Rn and that the testing was done at an ambient temp of 20 deg C.
