Instance Variables

stepVoltageIncrement
Tap step increment, in per cent of nominal voltage, per step position.

neutralStep
The neutral tap step position for this winding.

normalStep
The tap step position used in 'normal' network operation for this winding.

ltcFlag
Specifies whether or not a TapChanger has load tap changing capabilities.

neutralU
Voltage at which the winding operates at the neutral tap setting.

lowStep
Lowest possible tap step position, retard from neutral

regulationStatus
Specifies the default regulation status of the TapChanger.

highStep
Highest possible tap step position, advance from neutral

Method Details

init(self, stepVoltageIncrement=0.0, neutralStep=0, normalStep=0, ltcFlag=False, neutralU=0.0, lowStep=0, regulationStatus=False, highStep=0, 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.
neutralStep - The neutral tap step position for this winding.
normalStep - The tap step position used in 'normal' network operation for this winding. For a 'Fixed' tap changer indicates the current physical tap setting.
ltcFlag - Specifies whether or not a TapChanger has load tap changing capabilities.
neutralU - Voltage at which the winding operates at the neutral tap setting.
lowStep - Lowest possible tap step position, retard from neutral
regulationStatus - Specifies the default regulation status of the TapChanger. True is regulating. False is not regulating.
highStep - Highest possible tap step position, advance from neutral
RegulatingControl
