TransformerObservation

Common information captured during transformer inspections and/or diagnostics. Note that some properties may be measured through other means and therefore have measurement values in addition to the observed values recorded here.

dga

0..1

string

Dissolved Gas Analysis. Typical values are: Acceptable, Overheating, Corona, Sparking, Arcing.

freqResp

0..1

string

Frequency Response Analysis. Typical values are: acceptable, slight movement, significant movement, failed, near failure. A graphic of the response diagram, which is a type of document, may be associated with this analysis through the recursive document relationship of the ProcedureDataSet.

furfuralDP

0..1

string

Overall measure of furfural in oil and mechanical strength of paper. DP, the degree of polymerization, is the strength of the paper. Furfural is a measure of furfural compounds, often expressed in parts per million.

string

The level of oil in the transformer.

PropertiesCIMDataObject

ChangeSetMember

The single CIM data object in the appropriate dataset context.

aliasName

0..1

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.

description

0..1

string

The description is a free human readable text describing or naming the object. It may be non unique and may not correlate to a naming hierarchy.

mRID

0..1

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.

string

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