                                             RatioTapChanger

A tap changer that changes the voltage ratio impacting the voltage magnitude but not the phase angle across the transformer.

Method Details

[hide private]

init(self, stepVoltageIncrement=0.0, tculControlMode=`'reactive'`, *args, **kw_args)
(Constructor)

Initialises a new 'RatioTapChanger' instance.

Parameters:

stepVoltageIncrement - Tap step increment, in per cent of nominal voltage, per step position. For a symmetrical PhaseTapChanger, the stepVoltageIncrement is used in the formula for calculation of the phase angle. For a symmetrical PhaseTapChanger, the voltage magnitude does not change with tap step.
tculControlMode - Specifies the regulation control mode (voltage or reactive) of the RatioTapChanger. Values are: "reactive", "volt"

Overrides: object.__init__
