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.

Method Details

[hide private]

init(self, FromMeshImpedance=None, ToMeshImpedance=None, CoreAdmittance=None, StarImpedance=None, *args, **kw_args)
(Constructor)

Initialises a new 'TransformerEnd' instance.

Parameters:

FromMeshImpedance - All mesh impedances between this 'to' and other 'from' transformer ends.
ToMeshImpedance - All mesh impedances between this 'from' and other 'to' transformer ends.
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.
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).

Overrides: object.__init__

getCoreAdmittance(self)

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.

getStarImpedance(self)

(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).
