Class: PhaseTapChangerSymmetrical

name: PhaseTapChangerSymmetrical
description: Describes a symmetrical phase shifting transformer tap model in which
  the voltage magnitude of both sides is the same. The difference voltage magnitude
  is the base in an equal-sided triangle where the sides corresponds to the primary
  and secondary voltages. The phase angle difference corresponds to the top angle
  and can be expressed as twice the arctangent of half the total difference voltage.
