Describes a tap changer with a linear relation between the tap step and the phase angle difference across the transformer. This is a mathematical model that is an approximation of a real phase tap changer.<br/>The phase angle is computed as stepPhaseShitfIncrement times the tap position.<br/>The secondary side voltage magnitude is the same as at the primary side.<br/>
Attribute
Public AngleDegrees
  stepPhaseShiftIncrement
Details:
Notes: Phase shift per step position. A positive value indicates a positive phase shift from the winding where the tap is located to the other winding (for a two-winding transformer).<br/>The actual phase shift increment might be more accurately computed from the symmetrical or asymmetrical models or a tap step table lookup if those are available.<br/>
Public Reactance
  xMax
Details:
Notes: The reactance depend on the tap position according to a "u" shaped curve. The maximum reactance (xMax) appear at the low and high tap positions.<br/>
Public Reactance
  xMin
Details:
Notes: The reactance depend on the tap position according to a "u" shaped curve. The minimum reactance (xMin) appear at the mid tap position.<br/>
