Description
Operation
1=Enable
5=Disable
5=Disable
Operation Disable / Enable
CT connection type
1=Type 12=Type 2
1=Type 1
CT connection type. Determined by the directions of the
connected current transformers
Winding 1 type
1=Y 2=YN 3=D
4=Z 5=ZN
1=Y
Connection of the HV side windings. Determined by the
transformer connection group (e.g. Dyn11
“D”)
Winding 2 type
1=y2=yn3=d 4=z
5=zn
1=y
Connection of the LV side windings. Determined by the
transformer connection group (e.g. Dyn11
”yn”)
Clock number
0=Clk Num 0
1=Clk Num 1
2=Clk Num 2
4=Clk Num 4
5=Clk Num 5
6=Clk Num 6
7=Clk Num 7
8=Clk Num 8
10=Clk Num 10
11=Clk Num 11
0=Clk Num 0
Setting the phase shift between HV and LV with clock number
for connection group compensation (e.g. Dyn11
11)
Zro A elimination
1=Not eliminated
2=Winding
13=Winding
24=Winding 1 and
2
1=Not eliminated
Elimination of the zero-sequence current: 1
not eliminated,
2
on HV only, 3
on LV only, 4 -
both on HV and LV
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
13=Winding 2
1=Not in use
The winding where the tap changer is connected to. Also used
to enable/disable the automatic compensation of the tap
changer position (1 = Not in use; 2 = HV winding; 3 = LV
winding)
Step of tap
0.60...9.00
%
0.01
1.5
The percentage change in voltage corresponding one step of
the tap changer
CT ratio Cor Wnd 1
0.40...4.00
0.01
1
CT ratio correction, winding 1
CT ratio Cor Wnd 2
0.40...4.00
0.01
1
CT ratio correction, winding 2
