Variation in voltage magnitude (see below)

The linear part, is equivalent to the reflected voltage magnitude divided by the incident voltage magnitude.

The voltages between the three phases are the same in magnitude, however the voltage magnitudes between a particular phase and the neutral vary.

The line-to-line voltage magnitudes are all the same:

The device then computes the voltage angle, frequency, and voltage magnitude at 100 ms intervals.

In contrast the SVC's reactive output is proportional to the square of the voltage magnitude.

On the contrary, there are also unipolar switching effects where both set and reset operations require the same polarity, but different voltage magnitude.

Make an initial guess of all unknown voltage magnitudes and angles.

The voltage magnitude must be the same as the system voltage.

Reactive current is injected into the line to maintain voltage magnitude.
