Transformer end data.
No-load test results determine core admittance parameters. They include exciting current and core loss measurements from applying voltage to one winding. The excitation may be positive sequence or zero sequence. The test may be repeated at different voltages to measure saturation.

The name is any free human readable and possibly non unique text naming the object.
Losses measured from a zero-sequence excitation test.
Same definition as NoLoadTest.lossThe 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.
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.
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.
Voltage applied to the winding (end) during test.

Short-circuit test results determine mesh impedance parameters. They include load losses and leakage impedances. For three-phase windings, the excitation can be a positive sequence (the default) or a zero sequence. There shall be at least one grounded winding.

Apparent power that the winding can carry under emergency conditions (also called long-term emergency power).
Same definition as TransformerTest.basePowerWinding phase angle where 360 degrees are represented with clock hours, so the valid values are {0, ..., 11}. For example, to express the second winding in code 'Dyn11', set attributes as follows: 'endNumber'=2, 'connectionKind' = Yn and 'phaseAngleClock' = 11.
