Name URI Cardinality and Range Inheritance Description
angle cim:PhaseTapChangerTablePoint.angle 1..1 AngleDegrees direct The angle difference in degrees. A positive value indicates a positive angle variation from the Terminal at the PowerTransformerEnd, where the TapChanger is located, into the transformer.
PhaseTapChangerTable cim:PhaseTapChangerTablePoint.PhaseTapChangerTable 1..1 PhaseTapChangerTable direct The table of this point.
b cim:TapChangerTablePoint.b 0..1 PerCent TapChangerTablePoint The magnetizing branch susceptance deviation as a percentage of nominal value. The actual susceptance is calculated as follows:calculated magnetizing susceptance = b(nominal) * (1 + b(from this class)/100). The b(nominal) is defined as the static magnetizing susceptance on the associated power transformer end or ends. This model assumes the star impedance (pi model) form.
g cim:TapChangerTablePoint.g 0..1 PerCent TapChangerTablePoint The magnetizing branch conductance deviation as a percentage of nominal value. The actual conductance is calculated as follows:calculated magnetizing conductance = g(nominal) * (1 + g(from this class)/100). The g(nominal) is defined as the static magnetizing conductance on the associated power transformer end or ends. This model assumes the star impedance (pi model) form.
r cim:TapChangerTablePoint.r 0..1 PerCent TapChangerTablePoint The resistance deviation as a percentage of nominal value. The actual reactance is calculated as follows:calculated resistance = r(nominal) * (1 + r(from this class)/100). The r(nominal) is defined as the static resistance on the associated power transformer end or ends. This model assumes the star impedance (pi model) form.
ratio cim:TapChangerTablePoint.ratio 0..1 float TapChangerTablePoint The voltage at the tap step divided by rated voltage of the transformer end having the tap changer. Hence this is a value close to one.For example, if the ratio at step 1 is 1.01, and the rated voltage of the transformer end is 110kV, then the voltage obtained by setting the tap changer to step 1 to is 111.1kV.
step cim:TapChangerTablePoint.step 1..1 integer TapChangerTablePoint The tap step.
x cim:TapChangerTablePoint.x 0..1 PerCent TapChangerTablePoint The series reactance deviation as a percentage of nominal value. The actual reactance is calculated as follows:calculated reactance = x(nominal) * (1 + x(from this class)/100). The x(nominal) is defined as the static series reactance on the associated power transformer end or ends. This model assumes the star impedance (pi model) form.
