This emphasis on NET seems to be the place where the difficulties
begin. An (ideal) voltmeter placed at a voltage minima on the line
indicates a voltage of 0 volts. You appear to be saying that
despite this indication of 0, there is actually voltage present.

There are actually two voltages present of equal amplitude and
opposite phase. Their phasor sum is zero volts.

- how do I determine what these voltages actually are?

|Vfwd| = Sqrt(Pfwd*Z0) |Vref| = Sqrt(Pref*Z0)

If the voltmeter reads zero, these two voltages are equal in magnitude
and opposite in phase. Do you know how to sum two phasor voltages?
