In a PhaseTapChangerSymetrical tranformer the secondary side voltage magnitude is the same as at the primary side. The difference voltage magnitude, ΔU, is the base in an equal-sided triangle where the sides corresponds to the primary and secondary voltages. The phase angle difference correpsonds the top angle and can be expressed as follows α = 2arctan(ΔU/2)In a PhaseTapChangerSymetrical tranformer the secondary side voltage magnitude is the same as at the primary side.

Method Details

init(self, *args, **kw_args)
(Constructor)

Initialises a new 'PhaseTapChangerSymetrical' instance.

Parameters:

xMedian - The reactance at the mid tap step.
voltageStepIncrement - The voltage step increment on the out of phase winding. This voltage step on the out of phase winding of the phase shifter.
xMax - The reactance at the maximum tap step.

Overrides: object.__init__
