Inheritance

Attributes

Name URI Cardinality and Range Inheritance Description
nominalU cim:PetersenCoil.nominalU 1..1 Voltage direct The nominal voltage for which the coil is designed.
offsetCurrent cim:PetersenCoil.offsetCurrent 0..1 CurrentFlow direct The offset current that the Petersen coil controller is operating from the resonant point. This is normally a fixed amount for which the controller is configured and could be positive or negative. Typically 0 to 60 A depending on voltage and resonance conditions.
positionCurrent cim:PetersenCoil.positionCurrent 0..1 CurrentFlow direct The control current used to control the Petersen coil also known as the position current. Typically in the range of 20 mA to 200 mA.
xGroundMax cim:PetersenCoil.xGroundMax 1..1 Reactance direct The maximum reactance.
xGroundMin cim:PetersenCoil.xGroundMin 1..1 Reactance direct The minimum reactance.
xGroundNominal cim:PetersenCoil.xGroundNominal 1..1 Reactance direct The nominal reactance. This is the operating point (normally over compensation) that is defined based on the resonance point in the healthy network condition. The impedance is calculated based on nominal voltage divided by position current.
r cim:EarthFaultCompensator.r 0..1 Resistance EarthFaultCompensator Nominal resistance of device.
mRID cim:IdentifiedObject.mRID 1..1 string IdentifiedObject 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.
