A winding is associated with each defined terminal of a transformer (or phase shifter).- [R5.4], [R5.6], and [R5.10] are satisfied by navigation to ConnectivityNode and Substation - Each TransformerWinging must be contained by a PowerTransformer. Because a TransformerWinding (or any other object) can not be contained by more than one parent, a TransformerWinding can not have an association to an EquipmentContainer (Substation, VoltageLevel, etc). - The attributes ratedS, b0, g0, r0, x0, rground, xground, and connectionType are not required.

(Constructor)

 

Initialises a new 'TransformerWinding' instance.

Parameters:
  • x - Positive sequence series reactance of the winding. For a two winding transformer, the full reactance of the transformer should be entered on the primary (high voltage) winding.
  • x0 - Zero sequence series reactance of the winding.
  • b0 - Zero sequence magnetizing branch susceptance.
  • g0 - Zero sequence magnetizing branch conductance.
  • rground - Ground resistance path through connected grounding transformer.
  • b - Magnetizing branch susceptance (B mag). The value can be positive or negative.
  • connectionType - The type of connection of the winding. Values are: "I", "Yn", "Z", "Y", "A", "D", "Zn"
  • ratedS - The normal apparent power rating for the winding
  • r - Positive sequence series resistance of the winding. For a two winding transformer, the full resistance of the transformer should be entered on the primary (high voltage) winding.
  • r0 - Zero sequence series resistance of the winding.
  • ratedU - The rated voltage (phase-to-phase) of the winding, usually the same as the neutral voltage.
  • xground - Ground reactance path through connected grounding transformer.
  • windingType - The type of winding. Values are: "tertiary", "primary", "secondary"
  • RatioTapChanger - The ratio tap changer associated with the transformer winding.
  • PhaseTapChanger - The phase tap changer associated with the transformer winding.
  • PowerTransformer - A transformer has windings
