Method Details

init(self, stepVoltageIncrement=0.0, normalStep=0, neutralStep=0, subsequentDelay=0.0, regulationStatus=False, ltcFlag=False, highStep=0, initialDelay=0.0, lowStep=0, neutralU=0.0, SvTapStep=None, ImpedanceVariationCurve=None, TapSchedules=None, RegulatingControl=None, *args, **kw_args)
(Constructor)

Initialises a new 'TapChanger' 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.
normalStep - The tap step position used in 'normal' network operation for this winding. For a 'Fixed' tap changer indicates the current physical tap setting.
neutralStep - The neutral tap step position for this winding.
subsequentDelay - For an LTC, the delay for subsequent tap changer operation (second and later step changes)
regulationStatus - Specifies the default regulation status of the TapChanger. True is regulating. False is not regulating.
ltcFlag - Specifies whether or not a TapChanger has load tap changing capabilities.
highStep - Highest possible tap step position, advance from neutral
initialDelay - For an LTC, the delay for initial tap changer operation (first step change)
lowStep - Lowest possible tap step position, retard from neutral
neutralU - Voltage at which the winding operates at the neutral tap setting.
SvTapStep - The tap step state associated with the tap changer.
ImpedanceVariationCurve - A TapChanger can have an associated ImpedanceVariationCurve to define impedance variations with tap step changes.
TapSchedules - A TapChanger can have TapSchedules.
