Min winding tap -36...36 1 36 The tap position number resulting the
minimum number of effective winding
turns on the side of the transformer
where the tap changer is.
Max winding tap -36...36 1 0 The tap position number resulting the
maximum number of effective winding
turns on the side of the transformer
where the tap changer is.
Tap nominal -36...36 1 18 The nominal position of the tap changer
resulting the default transformation ratio
of the transformer (as if there was no tap
changer)
Tapped winding 1=Not in use
2=Winding 1
3=Winding 2
1=Not in use The winding where the tap changer is
connected to
Step of tap 0.60...9.00 % 0.01 1.50 The percentage change in voltage
corresponding one step of the tap changer
CT ratio Cor Wnd 1 0.40...4.00 0.01 1.00 CT ratio correction, winding 1
