                                         WindingTest

Physical winding test data for the winding/tap pairs of a transformer (or phase shifter). This test data can be used to derive other attributes of specific transformer or phase shifter models.

init(self, fromTapStep=0, leakageImpedance=0.0, noLoadLoss=0.0, phaseShift=0.0, excitingCurrent=0.0, loadLoss=0.0, toTapStep=0, voltage=0.0, From_TransformerWinding=None, To_TransformerWinding=None, *args, **kw_args)
(Constructor)

Initialises a new 'WindingTest' instance.

Parameters:

fromTapStep - The tap step number for the 'from' winding of the test pair.
leakageImpedance - The leakage impedance measured at the 'from' winding with the 'to' winding short-circuited and all other windings open-circuited. Leakage impedance is expressed in units based on the apparent power and voltage ratings of the 'from' winding.
noLoadLoss - The no load loss kW 'to' winding open-circuited) from the test report.
phaseShift - The phase shift measured at the open-circuited 'to' winding, with the 'from' winding set to the 'from' winding's rated voltage and all other windings open-circuited.
excitingCurrent - The exciting current on open-circuit test, expressed as a percentage of rated current, at nominal voltage
loadLoss - The load loss kW ('to' winding short-circuited) from the test report.
toTapStep - The tap step number for the 'to' winding of the test pair.
voltage - The voltage measured at the open-circuited 'to' winding, with the 'from' winding set to the 'from' winding's rated voltage and all other windings open-circuited.
From_TransformerWinding - The winding from which the test was conducted
To_TransformerWinding - The winding to which the test was conducted. Note that although the 'from' side of the test is required, the 'to' side of a test is not always required.

Overrides: object.__init__

getTo_TransformerWinding(self)

The winding to which the test was conducted. Note that although the 'from' side of the test is required, the 'to' side of a test is not always required.
