TransformerStarImpedance

Type: object

Transformer star impedance (Pi-model) that accurately reflects impedance for transformers with 2 or 3 windings. For transformers with 4 or more windings, TransformerMeshImpedance class shall be used.
For transmission networks use PowerTransformerEnd impedances (r, r0, x, x0, b, b0, g and g0).

root TransformerStarImpedance.r0 value
Type: number Default: null

nan

root IdentifiedObject.mRID
Type: string

Master resource identifier issued by a model authority. The mRID is unique within an exchange context. Global uniqueness is easily achieved by using a UUID, as specified in RFC 4122, for the mRID. The use of UUID is strongly recommended.
For CIMXML data files in RDF syntax conforming to IEC 61970-552, the mRID is mapped to rdf:ID or rdf:about attributes that identify CIM object elements.

root IdentifiedObject.name
Type: string

The name is any free human readable and possibly non unique text naming the object.

root TransformerStarImpedance.r
Type: object or number

Resistance of the transformer end.

Same definition as TransformerStarImpedance.r0

root IdentifiedObject.aliasName
Type: string

The aliasName is free text human readable name of the object alternative to IdentifiedObject.name. It may be non unique and may not correlate to a naming hierarchy.
The attribute aliasName is retained because of backwards compatibility between CIM relases. It is however recommended to replace aliasName with the Name class as aliasName is planned for retirement at a future time.

root TransformerStarImpedance.x
Type: object or number

Positive sequence series reactance of the transformer end.

root TransformerStarImpedance.x multiplier
Type: enum (of string) Default: "none"

nan

Same definition as multiplier

root TransformerStarImpedance.x unit
Type: enum (of string) Default: "ohm"

nan

Same definition as unit

root TransformerStarImpedance.x value
Type: number Default: null

nan

root TransformerStarImpedance.x0
Type: object or number

Zero sequence series reactance of the transformer end.

Same definition as TransformerStarImpedance.x
