High-voltage direct current lines are restricted only by thermal and voltage drop limits, since the phase angle is not material to their operation.
However, the relative phase angle between each pair of lines (1 to 2, 2 to 3,and 3 to 1) will still be −120°.
In this case the phase angle is the phase difference between the voltage applied to the impedance and the current driven through it.
Power factors are usually stated as "leading" or "lagging" to show the sign of the phase angle.
Since the power flow in a DC link is controlled independently of the phases of the AC networks at either end of the link, this phase angle limit does not exist, and a DC link is always able to transfer its full rated power.
The measured phase angle therefore depends on several biological factors.
