Mechanism for changing transformer winding tap positions.<br/>
Attribute
Public Boolean
  controlEnabled
Details:
Notes: Specifies the regulation status of the equipment.  True is regulating, false is not regulating.<br/>
Public Integer
  highStep
Details:
Notes: Highest possible tap step position, advance from neutral.<br/>The attribute shall be greater than lowStep.<br/>
Public Seconds
  initialDelay
Details:
Notes: For an LTC, the delay for initial tap changer operation (first step change)<br/>
Public Integer
  lowStep
Details:
Notes: Lowest possible tap step position, retard from neutral<br/>
Public Boolean
  ltcFlag
Details:
Notes: Specifies whether or not a TapChanger has load tap changing capabilities.<br/>
Public Integer
  neutralStep
Details:
Notes: The neutral tap step position for this winding.<br/>The attribute shall be equal or greater than lowStep and equal or less than highStep.<br/>
Public Voltage
  neutralU
Details:
Notes: Voltage at which the winding operates at the neutral tap setting.<br/>
Public Integer
  normalStep
Details:
Notes: The tap step position used in "normal" network operation for this winding. For a "Fixed" tap changer indicates the current physical tap setting.<br/>The attribute shall be equal or greater than lowStep and equal or less than highStep.<br/>
Public Float
  step
Details:
Notes: Tap changer position.<br/>Starting step for a steady state solution. Non integer values are allowed to support continuous tap variables. The reasons for continuous value are to support study cases where no discrete tap changers has yet been designed, a solutions where a narrow voltage band force the tap step to oscillate or accommodate for a continuous solution as input.<br/>The attribute shall be equal or greater than lowStep and equal or less than highStep.<br/>
Public Seconds
  subsequentDelay
Details:
Notes: For an LTC, the delay for subsequent tap changer operation (second and later step changes)<br/>
