Known Subclasses:

TransformerEnd is a conducting connection point of a power transformer. It corresponds to a physical transformer winding terminal. In earlier CIM versions, the TransformerWinding class served a similar purpose. This successor TransformerEnd class is more flexible and has important differences with TransformerWinding.TransformerEnd is a conducting connection point of a power transformer.

__init__(self, endNumber=0, rground=0.0, grounded=False, magBaseU=0.0, magSatFlux=0.0, bmagSat=0.0, xground=0.0, Terminal=None, FromWindingInsulations=None, CoreAdmittance=None, TransformerEndInfo=None, PhaseTapChanger=None, RatioTapChanger=None, FromMeshImpedance=None, ToWindingInsulations=None, ToMeshImpedance=None, StarImpedance=None, *args, **kw_args)
(Constructor)

 

Initialises a new 'TransformerEnd' instance.

Parameters:
  • endNumber - Number for this transformer end, corresponding to the end's order in the PowerTransformer.vectorGroup attribute. Highest voltage winding should be 1.
  • rground - (for Yn and Zn connections) Resistance part of neutral impedance where 'grounded' is true.
  • grounded - (for Yn and Zn connections) True if the neutral is solidly grounded.
  • magBaseU - The reference voltage at which the magnetizing saturation measurements were made
  • magSatFlux - Core magnetizing saturation curve knee flux level.
  • bmagSat - Core shunt magnetizing susceptance in the saturation region.
  • xground - (for Yn and Zn connections) Reactive part of neutral impedance where 'grounded' is true.
  • Terminal - External terminal of the power transformer to which this end belongs.
  • FromWindingInsulations
  • CoreAdmittance - Core admittance of this transformer end, representing magnetising current and core losses. The full values of the transformer should be supplied for one transformer end only.
  • TransformerEndInfo - Data for this transformer end.
  • PhaseTapChanger - Phase tap changer associated with this transformer end.
  • RatioTapChanger - Ratio tap changer associated with this transformer end.
  • FromMeshImpedance - All mesh impedances between this 'to' and other 'from' transformer ends.
  • ToWindingInsulations
  • ToMeshImpedance - All mesh impedances between this 'from' and other 'to' transformer ends.
  • StarImpedance - (accurate for 2- or 3-winding transformers only) Pi-model impedances of this transformer end. By convention, for a two winding transformer, the full values of the transformer should be entered on the high voltage end (endNumber=1).
