Comments

• OpenDSS Autotrans maps to CIM PowerTransformer + PowerTransformerEnd (one per winding), TransformerMeshImpedance (for short-circuit reactances XHX/XHT/XXT), and TransformerCoreAdmittance (no-load losses, winding 1 only). Key difference from regular Transformer: uses XHX/XHT/XXT naming instead of XHL/XHT/XLT; every winding is imported as connectionKind Y, grounded, with zero ground impedance (CIM has no explicit auto-transformer WindingConnection type). There is no dedicated Autotrans exporter; export of a converted PowerTransformer is handled by the same code path as a regular Transformer.

    comments:
    - 'Import: array form giving one %Xsc entry per winding pair, in the order produced
      by iterating pairs (i, k) with i < k over winding indices; each entry uses the
      same TransformerMeshImpedance formula as XHX (see XHX comments). Used in place
      of XHX/XHT/XXT for transformers with more than 3 windings. If fewer entries
      are given than there are winding pairs, the remaining pairs default to 10.0
      percent (higher than the default used for a regular Transformer). Export: for
      more than 3 windings, the generic Transformer exporter recovers the full pairwise
      list as Xscarray using the same convention in reverse (see XHX comments).'

description: A Autotrans object in OpenDSS representing an auto-transformer where
  the series and common windings share a magnetic core. Winding 1 is the series (high-side)
  winding; winding 2 is the common winding.
comments:
- 'OpenDSS Autotrans maps to CIM PowerTransformer + PowerTransformerEnd (one per winding),
  TransformerMeshImpedance (for short-circuit reactances XHX/XHT/XXT), and TransformerCoreAdmittance
  (no-load losses, winding 1 only). Key difference from regular Transformer: uses
  XHX/XHT/XXT naming instead of XHL/XHT/XLT; every winding is imported as connectionKind
  Y, grounded, with zero ground impedance (CIM has no explicit auto-transformer WindingConnection
  type). There is no dedicated Autotrans exporter; export of a converted PowerTransformer
  is handled by the same code path as a regular Transformer.'
