Default Description
36 The tap position number resulting the minimum
number of effective winding turns on the side of
the transformer where the tap changer is.
0 The tap position number resulting the
maximum number of effective winding turns on
the side of the transformer where the tap
changer is.
18 The nominal position of the tap changer
resulting the default transformation ratio of the
transformer (as if there was no tap changer)
1=Not in use The winding where the tap changer is
connected to. Also used to
1.50 The percentage change in voltage
corresponding one step of the tap changer
