Class Description

Tap changer data.

Attributes

Name	Type	Description
bil	Voltage	Basic Insulation Level (BIL) expressed as the impulse crest voltage of a nominal wave, typically 1.2 X 50 microsecond. This is a measure of the ability of the insulation to withstand very high voltage surges.
ctRating	CurrentFlow	Built-in current transformer primary rating.
ctRatio	Float	Built-in current transducer ratio.
frequency	Frequency	Frequency at which the ratings apply.
highStep	Integer	Highest possible tap step position, advance from neutral.
isTcul	Boolean	Whether this tap changer has under load tap changing capabilities.
lowStep	Integer	Lowest possible tap step position, retard from neutral.
neutralStep	Integer	The neutral tap step position for the winding.
neutralU	Voltage	Voltage at which the winding operates at the neutral tap setting.
ptRatio	Float	Built-in voltage transducer ratio.
ratedApparentPower	ApparentPower	Rated apparent power.
ratedCurrent	CurrentFlow	Rated current.
ratedVoltage	Voltage	Rated voltage.
stepPhaseIncrement	AngleDegrees	Phase shift per step position.
stepVoltageIncrement	PerCent	Tap step increment, in per cent of rated voltage, per step position.
