Array of OpenCircuitTest objects
No Additional ItemsOpen-circuit test results verify winding turn ratios and phase shifts. They include induced voltage and phase shift measurements on open-circuit windings, with voltage applied to the energised end. For three-phase windings, the excitation can be a positive sequence (the default) or a zero sequence.
No Additional PropertiesVoltage applied to the winding (end) during test.

Tap step number for the energised end of the test pair.
Tap step number for the open end of the test pair.
Voltage measured at the open-circuited end, with the energised end set to rated voltage and all other ends open.

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