To use R&X compensation, you have to enter the following line data:
▪ Ohmic resistance load in mΩ/m
▪ Inductive resistance load in mΩ/m
▪ Length of line in km
1. Go to Settings > Parameters > On-load tap-changer regulator > Com-
pensation.
2. Select the desired parameter.
3. Set the desired parameter.
4. Press the Accept button to save the modified parameter.
Ohmic resistance load
You can use this parameter to set the ohmic resistance load.
Inductive resistance load
You can use this parameter to set the inductive resistance load.
Length of line
You can use this parameter to set the length of line.
9.3.2.2 Z compensation
To keep the voltage constant for the consumer, you can use Z compensation
to activate a current-dependent voltage increase. You can also define a limit
value to avoid excess voltage on the transformer.
