This is a constant voltage source, specifying the complex voltage by the RMS voltage and the phase shift. The model has also the neutral cable, connected to a ground reference by default.
The parameters potentialReference and
definiteReference are used to define if the source
model should be selected as source for the reference angles
theta or not. More information about overdetermined
connectors can be found in Olsson Et Al.
(2008).
