Fields

transformer_connection: TransformerConnection

Transformer zero-sequence winding connection (FPQ-01).

Controls how zero-sequence current propagates through this transformer in the fault analysis zero-sequence Y-bus:

• WyeGWyeG (default): passes zero-sequence freely — same admittance as positive-seq.
• WyeGDelta: primary (from) side sees zero-seq shunt to ground; secondary blocked.
• DeltaWyeG: secondary (to) side sees zero-seq shunt to ground; primary blocked.
• DeltaDelta: transformer is skipped entirely in the zero-sequence Y-bus.
• WyeGWye: same as DeltaDelta — no zero-sequence path.

For transmission lines (non-transformers), this field is ignored.

winding_rated_kv: Option<f64>

Winding rated kV (individual winding, not line-to-line).

winding_rated_mva: Option<f64>

Winding rated MVA.

parent_transformer_id: Option<String>

Parent 3-winding transformer ID (star-bus expansion).

winding_number: Option<u8>

Winding number within parent transformer (1, 2, or 3).

winding_connection: Option<WindingConnection>

Winding connection type.

zn_winding: Option<Complex64>

Neutral impedance of this winding (pu, system base).

oil_temp_limit_c: Option<f64>

Oil temperature limit in deg-C (from CGMES OilTemperatureLimit, informational).

This is the transformer insulating oil temperature threshold at which the equipment is rated (PATL or TATL depending on OperationalLimitType). Stored per the CIM spec (OilTemperatureLimit attaches to ConductingEquipment via OperationalLimitSet). Not converted to MVA — requires equipment-specific thermal derating curves.

winding_temp_limit_c: Option<f64>

Winding temperature limit in deg-C (from CGMES WindingTemperatureLimit, informational).

Temperature threshold for the transformer winding insulation. Same structure as OilTemperatureLimit — stored per CIM spec, not converted to MVA.

impedance_limit_ohm: Option<f64>

Impedance limit in Ohms (from CGMES ImpedanceLimit, informational).

Represents a protection or operational limit on the series impedance magnitude. Stored per CIM spec (ImpedanceLimit attaches to ConductingEquipment via OperationalLimitSet). Not applied to the admittance model.
