TransformerEndInfo

Class Description

Transformer end data.

Attributes

Name	Type	Description
connectionKind	WindingConnection	Kind of connection.
emergencyS	ApparentPower	Apparent power that the winding can carry under emergency conditions (also called long-term emergency power).
endNumber	Integer	Number for this transformer end, corresponding to the end's order in the PowerTransformer.vectorGroup attribute. Highest voltage winding should be 1.
insulationU	Voltage	Basic insulation level voltage rating.
phaseAngleClock	Integer	Winding phase angle where 360 degrees are represented with clock hours, so the valid values are {0, ..., 11}. For example, to express the second winding in code 'Dyn11', set attributes as follows: 'endNumber'=2, 'connectionKind' = Yn and 'phaseAngleClock' = 11.
r	Resistance	DC resistance.
ratedS	ApparentPower	Normal apparent power rating.
ratedU	Voltage	Rated voltage: phase-phase for three-phase windings, and either phase-phase or phase-neutral for single-phase windings.
shortTermS	ApparentPower	Apparent power that this winding can carry for a short period of time (in emergency).
