No, you are correct. But I suspect you don't have the standard, which you really should have, because it specifies the necessary reference impedance, 0.4 + j0.25 ohms for single phase equipment. If you know the real and imaginary parts of the impedance of your generator, you can calculate the result that would be obtained with the reference impedance. -- Regards, John Woodgate, OOO - Own Opinions Only.
